10 women can do a work in 6 days and 6 men can do the same work in 5 days. If all these men and women work together, then how many days will they take to finish this work?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. .
Given:
10 women can do a work in 6 days and 6 men can do the same work in 5 days.
Calculations:
Let the efficiency of man and woman be M and W.
According to the question;
⇒ 10W × 6 = 6M × 5
⇒ M/W = 2/1
Total work = 10W × 6 = 10 × 1 × 6 = 60 units
Required number of days = 60/(10W + 6M)
⇒ 60/(10 + 12) = 60/22
⇒
