Question 2

A pie chart shows that 40% of a university's students study Science, 30% study Humanities, and 30% study Commerce. If there are 6,000 students in total, how many study Science?

Accepted Answer

2,400

Answer

6,000 × 0.40 = 2,400 Science students.

Question 3

A student earns R850 per week from a part-time job. After paying R200 for transport and R150 for food, what fraction of the original earnings remains?

Accepted Answer

1/2

Answer

Remaining: R850 - R200 - R150 = R500. Fraction: 500/850 = 10/17. Closest simple fraction: the exact answer is 10/17. Since "1/2" corresponds to 425, and 500 > 425, the answer is slightly more than 1/2. Selecting the closest standard fraction: none are exact. Best answer: 500/850 ≈ 0.588 ≈ 5/9 (0.556) or approximately 1/2 (0.5). The closest is 5/9 (index 1).

Answer

Mean: (450 + 510 + 480 + 540) ÷ 4 = 1,980 ÷ 4 = 495.
