| A is as efficient as B and C together. working together A and B can complete a work in 36 days and C alone can complete it in 60 clays. A and C work together for 10 days. B alone will complete the remaining work in:

A. 110 days

B. 90 days

C. 84 days

D. 88 days

### Right Answer is: A

#### SOLUTION

Efficiency of A = efficiency of (B + C)

Let the total work = LCM of 36, 60

= 180

One day’s efficiency of A + B =

One day’s efficiency of C =

A + B + C = 8 unit

2A = 8

A = 4

B = 1

C = 3

Work done by (A + C) in 10 days

Remaining work done by B in 110 days.
