Show answer & explanation
Correct answer: C
Answer: Rs. 6,000
Working:
Total salary of 75 workers = 5680 × 75 = 426000.
Salary of 25 workers = 5400 × 25 = 135000.
Salary of 30 workers = 5700 × 30 = 171000.
Number of remaining workers = 75 − 25 − 30 = 20.
Sum for remaining workers = 426000 − (135000 + 171000) = 120000.
Mean salary of remaining workers = 120000 ÷ 20 = 6000.
