Question 1Herons Formula

A municipal park in Delhi is triangular with side lengths 40 m, 24 m, and 32 m. The cost of planting grass at ₹5 per m² is:

Solution: The sides form a right triangle (24² + 32² = 40²). Area = ½ × 24 × 32 = 384 m². Cost = 384 × 5 = ₹1920.

Question 2Linear Equations

A rectangle is formed by the x-axis, y-axis, and the lines x = 6 and y = 5. What are the coordinates of the vertex diagonally opposite to the origin?

Solution: The four vertices of the rectangle are the origin (0,0), the point on the x-axis (6,0), the point on the y-axis (0,5), and the intersection point of x = 6 and y = 5, which is (6, 5). The corner diagonally opposite to (0,0) is (6, 5).

Question 3Number Systems 2

A rectangular rug has length 4√3 m and width 2√3 m. Its area is:

Solution: Area = 4√3 × 2√3 = 8 × 3 = 24 square metres.

Question 4Number Systems 1

A shop sells Kaju Katli at ₹400 × (256)^(1/4) per kg. What is the price of 1 kg?

Solution: (256)^(1/4) = (4⁴)^(1/4) = 4, so price = 400 × 4 = ₹1600.

Question 5Euclids Geometry

A system of axioms is said to be consistent if:

Solution: A system of axioms is consistent if no two axioms or deduced theorems contradict each other.

Question 6Lines And Angles

An angle is 30° less than twice its supplement. What is the angle?

Solution: Let the angle be x. Its supplement is 180° − x. x = 2(180° − x) − 30° → x = 360° − 2x − 30° → 3x = 330° → x = 110°.

Question 7Trigonometry

If sec θ = cosec θ for an acute angle, then θ is:

Solution: sec θ = cosec θ means cos θ = sin θ, which happens at 45°.

Question 8Probability

200 light bulbs include 6 defective ones. The probability that a randomly chosen bulb is defective is:

Solution: 6/200 = 3/100.

Question 9Polynomials

A cargo container has dimensions (x + 1), (x + 2) and (x + 3) metres. Its volume is:

Solution: (x + 1)(x + 2)(x + 3) = (x² + 3x + 2)(x + 3) = x³ + 6x² + 11x + 6.

Question 10Areas Related to Circles

A circular flower bed of radius 14 m is to be turfed at ₹5 per m² (π = 22/7). The cost is:

Solution: Area = 616 m²; cost = 616 × 5 = ₹3080.

Question 11Circles (Tangents)

A circular fountain is surrounded by a square whose sides each touch the fountain. Each side of the square is a tangent, so the side length equals:

Solution: A square circumscribing a circle has side equal to the diameter (the circle touches each side once).

Question 12Circles

A circular wire of radius 7 cm is cut and bent into the shape of a rectangle whose sides are in the ratio 4:7. The smaller side of the rectangle is:

Solution: Length of wire = Circumference = 2 × 22/7 × 7 = 44 cm. Perimeter of rectangle = 2(4x + 7x) = 22x. So, 22x = 44, which means x = 2. Smaller side = 4x = 4 × 2 = 8 cm.

Question 13Arithmetic Progressions

A clock strikes 1 at one o'clock, 2 at two o'clock, and so on up to 12. In twelve hours it strikes a total of:

Solution: 1 + 2 + … + 12 = 12 × 13 ÷ 2 = 78 times.

Question 14Surface Areas and Volumes

A cone of height 24 cm and radius of base 6 cm is made up of modeling clay. A child reshapes it in the form of a sphere. The radius of the sphere is:

Solution: Volume of cone = Volume of sphere. (1/3)πr²h = (4/3)πR³. (1/3)π(6²)(24) = (4/3)πR³. 36 × 24 = 4R³. 4R³ = 864 → R³ = 216 → R = 6 cm.

Question 15Statistics

A cricketer wants an average of 50 over 5 innings. After scoring 40, 55, 48 and 62, he needs in the 5th innings:

Solution: Total required = 250; he has 205, so he needs 45.

Question 16Coordinate Geometry

A food court is at (−3, 4) and a security booth is its mirror image across the x-axis. The booth's coordinates are:

Solution: Reflection in the x-axis: (−3, 4) → (−3, −4).

Question 17Real Numbers

A grocer wants to pack 24 ladoos, 36 barfis and 48 pedas so that each box has only one kind and the same, greatest number of sweets. Each box holds:

Solution: HCF(24, 36, 48) = 12 sweets per box.

Question 18Triangles

A guy wire is tied from the top of a 24 m pole to a point 7 m from its base. The wire's length is:

Solution: √(24² + 7²) = √625 = 25 m.

Question 19Areas of Parallelograms and Triangles

A kite is made of two triangular pieces of paper. The top triangle has base 30 cm and height 20 cm, and the bottom triangle has base 30 cm and height 10 cm. The total paper used is:

Solution: Top area = ½ × 30 × 20 = 300 cm². Bottom area = ½ × 30 × 10 = 150 cm². Total = 450 cm².

Question 20Quadrilaterals

A logic rule states: 'All squares are rectangles, and all rectangles are parallelograms.' Based on this rule, which statement is logically FALSE?

Solution: A rhombus does not necessarily have 90° angles, so not all rhombuses are squares. Hence, this statement is false.

Question 21Pair of Linear Equations in Two Variables

A pair of linear equations has a unique solution when:

Solution: The lines intersect at one point exactly when a₁/a₂ ≠ b₁/b₂.

Question 22Quadratic Equations

A rectangle's length is 5 m more than its width and its area is 84 m². The width is:

Solution: w(w + 5) = 84 gives w² + 5w − 84 = (w + 12)(w − 7) = 0, so w = 7 m.

Question 23Linear Equations in Two Variables

A small firm sells handmade items. The profit (y) earned is given by y = 25x − 800, where x is the number of items sold. How many items must be sold to reach a break-even point (zero profit)?

Solution: Break-even means profit y = 0. Set 0 = 25x − 800 → 25x = 800 → x = 800/25 = 32 items.

Question 24Heron's Formula

A square has a side of 10 cm and a diagonal of 10√2 cm. The area calculated by summing the two triangles via Heron's formula is:

Solution: Each triangle has sides 10, 10, 10√2. Area of one = ½ × base × height = 50. Total = 100 cm² (validating standard area 10² = 100).

Question 25Euclid's Geometry

A tailor has a template cardboard triangle for cutting pockets. He places the template directly over a piece of cloth and finds that it covers the cloth triangle perfectly with no edges sticking out. He concludes that the cloth triangle is exactly equal in size to the template. Which axiom supports this?

Solution: Euclid's Fourth Axiom states: 'Things which coincide with one another are equal to one another.' Superimposing and covering perfectly means they coincide.

Question 26Lines & Angles

An angle is equal to one-third of its supplement. Find the measure of its supplement.

Solution: Let the supplement angle be x. The angle itself is x/3. Since they are supplementary, x + x/3 = 180° → 4x/3 = 180° → 4x = 540° → x = 135°.

Question 27Number Systems

An irrational number lying between 2 and 2.5 is:

Solution: Since 2² = 4 and 2.5² = 6.25, a non-perfect-square root between them works: √5 (because 4 < 5 < 6.25).

Question 28Introduction to Trigonometry

If sin θ = 3/5, then cos θ equals:

Solution: cos θ = √(1 − 9/25) = √(16/25) = 4/5.

Question 29Areas Related To Circles

A circular garden of radius 21 m has a 90° sector reserved for roses. The rose area (π = 22/7) is:

Solution: (90/360)(22/7)(441) = (1/4)(1386) = 346.5 m².

Question 30Surface Areas Volumes

A conical heap of sand has base radius 12 m and height 5 m (π = 22/7). Its slant height is:

Solution: l = √(12² + 5²) = √169 = 13 m.

Question 31Coding-Decoding

If in a code BIRD is written as 2-9-18-4 using letter positions, what is the code for FISH?

Solution: Each letter is replaced by its alphabet position: F=6, I=9, S=19, H=8, giving 6-9-19-8. Hence the answer is 6-9-19-8.

Question 32Blood Relations

Pointing to a man, Reena said, 'He is the son of my grandfather's only child.' How is the man related to Reena?

Solution: Reena's grandfather's only child is Reena's parent. The son of Reena's parent is Reena's brother. Hence the man is Reena's brother.

Question 33Blood Relations

A is the brother of B. B is the brother of C. C is the father of D. How is A related to D?

Solution: A and B are brothers of C, so A is C's brother. C is D's father, so A (C's brother) is D's uncle. Hence A is D's uncle.

Question 34Blood Relations

Introducing a woman, Sunil said, 'She is the mother of the only daughter of my son.' How is the woman related to Sunil?

Solution: The only daughter of Sunil's son is Sunil's granddaughter. The granddaughter's mother is the wife of Sunil's son, i.e., Sunil's daughter-in-law. Hence she is his daughter-in-law.

Question 35Blood Relations

P is the wife of Q. R is the son of P. S is the brother of Q. How is S related to R?

Solution: Q is R's father (Q is P's husband and R is P's son). S is Q's brother, so S is R's paternal uncle. Hence S is R's uncle.

Question 36Direction & Distance

A man walks 5 km north, then turns right and walks 3 km, then turns right again and walks 5 km. How far and in which direction is he from the starting point?

Solution: He goes 5 km north, 3 km east (right from north), then 5 km south (right from east). The north and south legs cancel, leaving him 3 km east of the start. Hence he is 3 km East.

Question 37Direction & Distance

A car travels 6 km east, then 8 km north. What is the shortest distance between the starting and ending points?

Solution: The two legs are perpendicular, so the shortest distance is the hypotenuse: sqrt(6^2 + 8^2) = sqrt(36 + 64) = sqrt(100) = 10 km. Hence 10 km.

Question 38Direction & Distance

Rohan faces north. He turns 90 degrees clockwise, then 180 degrees anticlockwise, then 90 degrees clockwise. Which direction is he facing now?

Solution: Start north. 90 clockwise gives east. 180 anticlockwise gives west. 90 clockwise gives north. Hence he faces North.

Question 39Syllogism

Statements: All pens are pencils. All pencils are erasers. Conclusions: I. All pens are erasers. II. All erasers are pens. Which conclusion follows?

Solution: From 'all pens are pencils' and 'all pencils are erasers', it follows that all pens are erasers (I follows). Conclusion II reverses the relation and is not valid. Hence only I follows.

Question 40Syllogism

Statements: Some cats are dogs. All dogs are animals. Conclusions: I. Some cats are animals. II. All cats are animals. Which conclusion follows?

Solution: Some cats are dogs and all dogs are animals, so those cats which are dogs are animals; thus 'some cats are animals' follows. 'All cats are animals' is not guaranteed. Hence only I follows.

Question 41Syllogism

Statements: No book is a table. All tables are chairs. Conclusions: I. No book is a chair. II. Some chairs are not books. Which conclusion follows?

Solution: All tables are chairs and no book is a table, so those chairs which are tables are not books, giving 'some chairs are not books' (II follows). 'No book is a chair' cannot be concluded because a book could still be a chair. Hence only II follows.

Question 42Order & Ranking

In a row of 40 students, Ravi is 12th from the left end. What is his position from the right end?

Solution: Position from right = Total - position from left + 1 = 40 - 12 + 1 = 29. Hence Ravi is 29th from the right end.

Question 43Order & Ranking

In a class, Anil ranks 7th from the top and 18th from the bottom. How many students are there in the class?

Solution: Total students = (rank from top) + (rank from bottom) - 1 = 7 + 18 - 1 = 24. Hence there are 24 students.

Question 44Order & Ranking

Five friends sit on a bench. P is to the left of Q but to the right of R. S is to the right of Q but to the left of T. Who sits in the middle?

Solution: From the clues the left-to-right order is R, P, Q, S, T. The person in the middle (3rd position) is Q. Hence Q sits in the middle.

Question 45Seating arrangement

Six people A, B, C, D, E, F sit in a row facing north. C is at the left end. B is immediately to the right of C. A is third to the right of B. F is immediately to the left of A, and D is to the right of A. Who sits at the right end?

Solution: C is at position 1, B at 2. A is third to the right of B, so A is at position 5. F is immediately left of A, so F is at 4. Position 3 is left for E, and D is to the right of A, so D is at position 6, the right end. The order is C, B, E, F, A, D. Hence D is at the right end.

Question 46Seating arrangement

Five children sit in a line. M is exactly between N and O. P is at the left end and N is immediately next to P. The fifth child Q takes the only remaining seat. Who is at the right end?

Solution: P is at the left end and N is next to P, so the order starts P, N. M is between N and O, giving P, N, M, O. The fifth child Q takes the remaining right-end seat: P, N, M, O, Q. Hence Q is at the right end.

Question 47Venn diagram

Which option best represents the relationship among: Animals, Dogs, Cats?

Solution: Dogs and cats are distinct kinds of animals with no overlap between them, but both are entirely contained within the larger category Animals. Hence the correct diagram has two non-overlapping circles inside a bigger Animals circle.

Question 48Venn diagram

Choose the diagram that shows the relationship among: Doctors, Women, Mothers.

Solution: All mothers are women, so Mothers is a circle wholly inside Women. Some doctors are women (and some are mothers), so the Doctors circle overlaps both. Hence option A is correct.

Question 49Mathematical operations

If + means x, x means -, - means /, and / means +, find the value of: 6 + 4 x 2 / 8.

Solution: Replace symbols: + becomes x, x becomes -, / becomes +. So 6 + 4 x 2 / 8 becomes 6 x 4 - 2 + 8 = 24 - 2 + 8 = 30. Hence the answer is 30.

Question 50Mathematical operations

If A means +, B means -, C means x, and D means /, what is the value of 12 C 3 A 6 B 4?

Solution: Replace: C is x, A is +, B is -. So 12 x 3 + 6 - 4 = 36 + 6 - 4 = 38. Hence the answer is 38.

Question 51Statement & Conclusions

Statement: The government has banned the use of plastic bags in the city. Conclusions: I. People will look for alternatives to plastic bags. II. The ban will help reduce plastic pollution in the city. Which conclusion follows?

Solution: With plastic bags banned, people will need alternatives (I is a reasonable consequence), and reducing plastic use logically helps reduce plastic pollution (II). Hence both conclusions follow.

Question 52Statement & Assumptions

Statement: A notice in an office reads, 'Please switch off the lights when you leave the room.' Assumptions: I. Leaving lights on wastes electricity. II. People sometimes forget to switch off lights. Which assumption is implicit?

Solution: The notice exists because leaving lights on is considered wasteful (I) and because people may forget to turn them off, otherwise the reminder would be pointless (II). Hence both assumptions are implicit.

Question 53Statement & Conclusions

Statement: All the trains were running late due to heavy fog. Conclusions: I. Fog can affect train schedules. II. No train ever runs on time. Which conclusion follows?

Solution: The statement shows fog caused delays, so 'fog can affect train schedules' follows (I). 'No train ever runs on time' is an overgeneralisation not supported by one fog incident, so II does not follow. Hence only I follows.

Question 54Missing number (matrix)

In a 2x2 grid the entries are squares of consecutive integers. The top row reads 4 and 9, and the bottom row reads 16 and ?. What number replaces the question mark?

Solution: The numbers are squares of 2, 3, 4, 5: 4=2^2, 9=3^2, 16=4^2, so the missing number is 5^2 = 25. Hence the answer is 25.

Question 55Missing number (matrix)

A grid has three rows. Row 1: (3, 5, 15). Row 2: (4, 6, 24). Row 3: (7, 8, ?). In each row the third number is the product of the first two. Find the missing number.

Solution: In each row the third entry equals the product of the first two: 3x5=15, 4x6=24, so 7x8=56. Hence the answer is 56.

Question 56Missing number (matrix)

Three columns each have a top, middle and bottom number, where bottom = top divided by middle. The columns are (8, 4, 2), (18, 9, 2) and (24, ?, 2). Find the missing middle number.

Solution: Since bottom = top / middle, the middle = top / bottom = 24 / 2 = 12 (check: 8/4=2, 18/9=2). Hence the missing number is 12.

Question 57Word formation

How many meaningful English words can be formed using all the letters of the word 'OWN', each letter used exactly once?

Solution: Using O, W, N exactly once we can form 'OWN' and 'WON', which are both meaningful English words. That is two words. Hence the answer is Two.

Question 58Word formation

Which of the following words can be formed using only the letters of the word 'TRIANGLE'?

Solution: TRIANGLE contains T, R, I, A, N, G, L, E. 'INTEGRAL' uses I, N, T, E, G, R, A, L, each available once. The others need repeated or absent letters (e.g., GARLAND needs two A's and a D). Hence the answer is INTEGRAL.

Question 59Counting figures

A rectangle is divided by one horizontal and one vertical interior line into four smaller rectangles. How many rectangles are there in the figure altogether?

Solution: Including the borders there are 3 horizontal and 3 vertical lines. Number of rectangles = 3C2 x 3C2 = 3 x 3 = 9. Hence there are 9 rectangles.

Question 60Counting figures

In a triangle, all three medians are drawn from the vertices to the midpoints of the opposite sides, meeting at the centroid. Into how many small triangles is the original triangle divided?

Solution: The three medians divide the triangle into 6 smaller triangles of equal area. Hence the answer is 6.
