A and B working together can finish a project in 16 days while B alone can do it in 24 days. In how many days can A alone finish the project ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 48 days.
A and B working together can finish a project in 16 days while B alone can do it in 24 days.
L.C.M(16 and 24) = 48
The efficiency of A and B = 48/16 = 3 units
The efficiency of B = 48/24 = 2 units
Thus, the efficiency of A = 3 - 2 = 1 unit
Time taken by A = 48/1 = 48 days
