Correct Answer - Option 1 : 96 days
Given:
A can complete the work in 32 days
B is 2/3 as efficient as A
Calculation:
Let the efficiency of A and B be 3x and 2x respectively.
Work done by A in 32 days = 32 × 3x = 96x
Total work = 96x
Time taken by B to complete the twice work = ( 2 × 96x)/2x days
⇒ 96 days
∴ B will complete twice the work in 96 days
