Moderate
A contractor employs 20 male, 15 female and 5 children in his factory. Male wages are Rs. 10 per day, female Rs. 8 per day, and children Rs. 3 per day. The weighted x of wages paid per day will be_____________?
Correct answer: B. 8.37
- A. 3.86
- B. 8.37
- C. 9.21
- D. 10.63
Explanation
The weighted mean wage is total daily wages divided by total workers: (20×10 + 15×8 + 5×3) / 40 = 335/40 = 8.375, approximately Rs. 8.37. Equal weighting would be inappropriate because the groups have different sizes.
