20 men can do a job in 10 days, working 8 hours a day. If women are 33.33% more efficient than men, how many women will it take to finish the same job in 10 days, working 6 hours a day?

A) 10
B) 12
C) 15
D) 20

Answer & Explanation:

D) 20.
Total men hours of work = 20 × 10 × 8 = 1600
So 1 man, 1 hr work = 1/1600
As woman is 33.33% more efficient, so 1 woman,
1 hr work=(133.33/100) x (1/1600)=1.3333/1600
So 10 days work of 1 woman working 6
=10 × 6 × (1.3333/1600)
= 1/20
Hence 20 women are required.
