14. Obadalla woke up 20 minutes past the time shown on the clockface below. What time did he wake up?

Read the time on the clock.
The hour hand is between 6 and 7, and the minute hand is pointing at 7. This indicates 6:35.
The question states "20 minutes past the time shown".
In this context, given the options, "past" is likely used to mean 20 minutes before the time shown.
Subtract 20 minutes from 6:35.
$6:35 - 20 \text{ minutes} = 6:15$ .
The correct option is A.
$\boxed{\text{A. } 6:15}$
15. Daniel sold $\frac{4}{5}$ of his cows. What percentage of his cows did he sell?

$V = (10 \text{ cm})^3$
Calculate the volume.
$V = 10 \text{ cm} \times 10 \text{ cm} \times 10 \text{ cm} = 1000 \text{ cm}^3$
The correct option is D.
$\boxed{\text{D. } 1000 \text{ cm}^3}$
21. An athlete covered 18.296 km. Round off the distance covered to the nearest hundredths.
Identify the hundredths place, which is the digit 9 in 18.296.
Look at the digit immediately to the right of the hundredths place, which is 6 (in the thousandths place).
Since 6 is 5 or greater, round up the hundredths digit.
The 9 rounds up to 10, so we carry over 1 to the tenths place.
$18.296 \approx 18.30$ .
The correct option is A.
$\boxed{\text{A. } 18.30}$
22. In Mlima Primary School there are 496 learners. Each learner was given 12 exercise books and five textbooks. How many in total were given out?

Calculate the total number of textbooks given out.
Total textbooks $= 496 \text{ learners} \times 5 \text{ textbooks/learner} = 2480 \text{ textbooks}$ .
Add the total number of exercise books and textbooks.
Total items given out $= 5952 + 2480 = 8432$ .
The correct option is D.
$\boxed{\text{D. } 8432}$
23. Work out the square root of: $\sqrt{625}$
Find a number that, when multiplied by itself, equals 625.
We know that $20^2 = 400$ and $30^2 = 900$ . The number must end in 5, so it could be 25.
Test 25.
$25 \times 25 = 625$ .
So, $\sqrt{625} = 25$ .
The correct option is B.
$\boxed{\text{B. } 25}$
24. A square has an area of $144 \text{ m}^2$ . What is its perimeter?
