13 1 days 2 -
13 1 days 3 - 10 days
Correct Option: C
According to the question
5 men = 8 women
| ∴ 2 men = | × 2 = | women | ||
| 5 | 5 |
| ∴ Total women = | + 4 = | women | ||
| 5 | 5 |
∴ No. of days to do the same work
| = | = | |||
| 36/5 | 36 |
| = | = 13 | days | ||
| 3 | 3 |
Aliter : Using Rule 12,
Here, A = 5, B = 8, a = 12
A1 = 2 and B1 = 4
| Time taken = | A1B + B1A |
| = | 2 × 8 + 4 × 5 |
| = | 36 |
| = 33 | days | 3 |
