Correct option is B
Given:
25 women can complete a task in 60 days.
We need to determine after how many days 5 more women should join so that the task is completed in 55 days.
Formula Used:
M = Number of Workers, D = Days , H = Hours, W = Work
Solution:
Let , 5 more women join the work after x days.
= 25x + 30(55 - x)
1500 = 25x + 1650 - 30x
-5x + 1650 = 1500
-5x = -150
x = 30 days
5 more women should join after 30 days.
