Anil and Bipin together can complete a work in 15 days, while Bipin alone can finish it in 20 days. In how many days can Anil alone finish the work?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 60.
Given:
Anil and Bipin together can complete a work in 15 days.
Bipin alone can finish it in 20 days.
Calculations:
Total work (L.C.M of 15 and 20) = 60 units
The efficiency of Anil and Bipin = 60/15 = 4
The efficiency of Bipin = 60/20 = 3
So,
The efficiency of Anil = 4 - 3 = 1 unit
Time taken by Anil to finish the work = 60/1 = 60 days
