Question
A woman is one-third as efficient as a man. How much time
will 9 women take to complete a job that is 75% of the work done by 10 men in 12 days?Solution
ATQ,
Let the efficiency of each man be 3x units/day
So, total work = 3x × 10 × 12 = 360x units
And efficiency of a woman = 3x ÷ 3 = x units/day
So, required time = (360x × 0.75) ÷ (9 × x) = 30 days
