Show answer & explanation

Correct answer: D

Concept

In data-interpretation problems, the percentage on the line graph links a company's managers to its total workforce: managers = (manager %) × total employees, so total employees = managers ÷ (manager %). A part-ratio (male : female) fixes the manager count once one part is known, because each ratio unit equals the same head-count.

Application

  1. Read the data for company F from the two sources: the line graph gives the manager percentage as 18%, and the table gives the number of female managers as 18.

  2. Use the male : female ratio 7 : 2. The 2 female-parts correspond to 18 female managers, so one ratio unit = 18 ÷ 2 = 9 managers, and the 7 male-parts give 7 × 9 = 63 male managers.

  3. Add the parts to get the total managers: 63 + 18 = 81 managers (equivalently, 9 units × 9 = 81).

  4. Convert the manager count to the workforce using the 18% figure: total employees = 81 ÷ 0.18 = 450.

  5. Non-managers are the rest of the workforce: 450 − 81 = 369.

Cross-check

Non-managers form the remaining 100% − 18% = 82% of the workforce. Checking directly: 82% of 450 = 0.82 × 450 = 369, which matches the subtraction. Hence the number of non-manager employees in company F is 369.
