Question

1. 20 men and 25 women together can complete a work in 5 days. It takes 150 days for one man
alone to complete the work. How many days will be required for one woman to complete the
same work?

A) 300 B) 325 C) 350 D) 375​

Answer 1

Answer:

375

Step-by-step explanation:

(20M+25W)*5=150*M

50M=125W

2M=5W

now, as 1man can do the work in 150 days therefore 2 man can do it in 75 days.

now since 2M and 5W are same therefore 5W can do it in 75 days therefore 1 women can do it in 75*5 which is 375 days
