Question

The mean wage of 100 workers is Rs 324. The mean wage of 60 workers is Rs 340. Find the mean wage of the remaining 40 workers

Answer 1

Explanation:

Mean wages of 40 worker = 300

Explanation:

Given:

Mean wages of 100 worker = 324

Total wages of 100 worker = 324 × 100 = 32,400

Mean wages of 60 worker = 340

Total wages of 60 worker = 340 × 60 = 20,400

Find:

Mean wages of 40 worker

Computation:

Mean wages of 40 worker = [Total wages of 100 worker - Total wages of 60 worker] / 40

Mean wages of 40 worker = [32,400 - 20,400] / 40

Mean wages of 40 worker = [12,000] / 40

Mean wages of 40 worker = 300
