Question
4 girls together are as efficient as one man. If 32
girls can complete 40 garments in 5 days, how many men are needed to complete the same work in 2 days?Solution
ATQ,
Let the efficiency of each girl be 'x' units/day
Efficiency of each man = 4x units/day
Let the number of men required be 'm'
(32x × 5)/40 = (4x × m × 2)/40
⇒ 8m = 160
⇒ m = 20
Therefore, 20 men are required to complete the work in 2 days.
