A and B together complete work in 6 days.
A complete work in 10 days.
Formula Used :
Work Done = time × efficiency
Calculation :
A + B = 6 days
A = 10 days
LCM of (10, 6) = 60 days
Efficiency of A + B = 10 days
Efficiency of A = 6 days
Efficiency of B = 10 - 6 = 4 days
Time taken by B = 60/4 = 15 days
∴ The correct answer is 15 days.
