2 L 500 mL − 1 L = 1 L 500 mL.
Q9 Logical Reasoning
2 p.m. in 24-hour time is ___ ?
2 + 12 = 14, so 14:00.
Q10 Achievers Section
How many minutes are there in 2 hours 15 minutes?
2 × 60 = 120, plus 15 = 135 minutes.
Q11 Logical Reasoning
What is 0.25 + 0.25?
0.25 + 0.25 = 0.5.
Q12 Achievers Section
On a bar graph with scale 20, the tallest bar is 3 units and the shortest is 1 unit. What is the difference in value?
Tallest = 60, shortest = 20, so 60 − 20 = 40.

Q24 Mathematical Reasoning
Change 6000 m into kilometres.
6000 ÷ 1000 = 6 km.
Q25 Logical Reasoning
Continue the pattern: 0.1, 0.2, 0.3, ___ ?
Add one tenth: 0.3 + 0.1 = 0.4.
Q26 Logical Reasoning
Which number is divisible by 3?
Digit sum of 27 is 2 + 7 = 9, which is divisible by 3.
Q27 Mathematical Reasoning
If the radius is 7 cm, the diameter is ___ ?
Diameter = 2 × 7 = 14 cm.
Q28 Everyday Mathematics
A square field has side 20 m. How much fencing is needed to go around it?
Perimeter = 4 × 20 = 80 m.
Q29 Everyday Mathematics
Beads repeat red, blue, green. What colour is the 7th bead?
The pattern repeats every 3, so the 7th bead is red (same as the 1st).
Q30 Mathematical Reasoning
In 4.56, what is the value of the digit 5?
5 is in the tenths place, so it stands for 0.5.
