A factory has 100 workers, of whom 40% are women. The average monthly salary of women is ₹50,000, while men earn ₹60,000 on average. What is the overall average monthly salary of the workforce (in ₹000s)?

1. 56
2. 56.5
3. 57
4. 57.5

Correct answer: 56

Solution

There are 40 women and 60 men. Total salary = 40 × 50,000 + 60 × 60,000 = ₹56,00,000. Dividing by 100 workers gives an average of ₹56,000, i.e. 56 in ₹000s.
