Explanation

Let woman's efficiency be 100%. Then man's efficiency = 150% (50% more than woman) and boy's efficiency = 80% (20% less than woman). Total efficiency = 100 + 150 + 80 = 330%. Wages are distributed in proportion to efficiency. Boy's share = (80/330) × 3300 = 800. The boy's efficiency is 80/330 of total, so his wage is the same fraction of total wages.
