If A can complete a work in 10 days and B is 100 faster than A.
How much time B will take to complete the work?
20days
21days
22days
30days
Explanation:
Men at work earlier = 10
Men at work later = 5
Ration of workers = a : b = 2 : 1
10 men can perform the complete task = 10 days
5 men will perform the same task in = b : a time = 1 : 2 => 20 days.
