A and B can complete a piece of work in 15 days and 10 days respectively. They contracted to complete the work for ₹ 30,000. The share of A in the contracted money will be :
-
- ₹ 18,000
- ₹ 16,500
- ₹ 12,500
- ₹ 12,000
Correct Option: D
| A’s 1 day’s work = | 15 |
| B’s 1 day’s work = | 10 |
| Ratio = | : | = 2 : 3 | ||
| 15 | 10 |
Sum of the ratios = 2 + 3 = 5
∴ A’s share
| = ₹ | × 30000 = ₹ 12000 | 5 |
Aliter : Using Rule 24,
Here, m = 15, n = 10, R = 30,000
| Share of A = | × R | m + n |
| = | × 30000 | 15 + 10 |
| = | × 30000 = ₹ 12,000 | 25 |
