Three men can complete a piece of work in 6 days. Two days after they started the work, 3 more men joined them. How many days will they take to complete the remaining work ?
-
- 1 days
- 2 days
- 3 days
- 4 days
Correct Option: B
| Work done in two days = | × 2 | 6 |
| = | , remaining work = | |||
| 3 | 3 |
| ⇒ | = | |||
| W1 | W2 |
| ⇒ | = | |||
| 3 | 3 |
| ⇒ D2 = | = 2 days | 6 |
Aliter : Using Rule 10,
Here, A = 3, a = 6
b = 2, B = 3
| Required time = | A + B |
| = | 3 + 3 |
| = | = 2 days | 6 |
