Question 43

Data Presentation

On a pie chart, there are four sectors of which three angles are 45°, 90° and 135°. If the smallest sector represents N28.00, how much is the largest sector?

  1. A.N96.00
  2. B.N84.00
  3. C.N48.00
  4. D.N42.00
Show the answer and explanation

Answer: B (N84.00)

Explanation

The fourth angle is 90°, so the largest sector is 135°, three times the smallest (45°): 3 × N28 = N84.
