A and B together can do a work in 16 days. If A alone can do the same work in 48 days, then in how many days can B alone do the same work?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 24.
LCM(16, 48) = 48
The efficiency of A and B = 48/16 = 3 units
The efficiency of A = 48/48 = 1 unit
The efficiency oof B = 3 - 1 = 2 units
Time taken by B = = 24 days
