Correct answer: D

Concept

When a group total and its percentage are known, the count in that group is total × percentage ÷ 100. The average of n values is their sum divided by n. The percent by which A is more than a reference B is (A − B) ÷ B × 100.

Application

  1. Production PG employees = 3000 × 40 ÷ 100 = 1200.

  2. Marketing PG employees = 2000 × 60 ÷ 100 = 1200.

  3. HR PG employees = 300 × 80 ÷ 100 = 240.

  4. Average PG employees = (1200 + 1200 + 240) ÷ 3 = 2640 ÷ 3 = 880.

  5. The Finance department has 600 employees, so the percent more is (880 − 600) ÷ 600 × 100 = 46.666…%, which is approximately 46.67%.

Cross-check

Increasing 600 by 46.67% gives 600 × (1 + 46.67 ÷ 100) ≈ 880.02, which rounds to the computed average of 880.

Result

Therefore, the required approximate percentage is 46.67%.
