If 3 men or 6 women can do a piece of work in 16 days, in how many days can 12 men and 8 women do the same piece of work?
-
- 4 days
- 5 days
- 3 days
- 2 days
Correct Option: C
3m = 6w
∴ 1m = 2w
12m + 8w = (12 × 2w) + 8w = 32w
∴ 6 women can do the work in 16 days.
∴ 32 women can do the work in
| = 3 days | 32 |
Aliter : Using Rule 12,
Here, A = 3, B = 6, a = 16
A1 = 12, B1 = 8
| Time taken = | A1B1 + B1A |
| = | 12 × 6 + 8 × 3 |
| = | = 3 days | 96 |
