Explanation
The correct answer is Option 1 i.e. 100 days.
| Understanding/Application |
|
A and B can do 30% of the work in 6 days. A and B can do 100% of the work in 20 days. Let the total work to be done be x. Work done by A and B together in 1 day = x/20 |
|
B alone can do the same work in 25 days. Work done by B alone in 1 day = x/25 Work done by A alone in 1 day = x/20 - x/25 = x/100 Days required by A to alone complete the work = 100 days |
