| A and B can complete a piece of work in 15 days and 10 days respectively. They contracted to complete the work for Rs. 30000. The share of A in the contracted money will be |
A) Rs. 18000
B) Rs. 16500
C) Rs. 12500
D) Rs. 12000
Correct Answer: D
Solution :
| A's 1 day's works \[=\frac{1}{15}\] |
| B's 1 day's works \[=\frac{1}{10}\] |
| Ratio \[=\frac{1}{15}:\frac{1}{10}=2:3\] |
| Sum of the ratios \[=2+3=5\] |
| \[\therefore \] A's share \[=Rs.\frac{2}{5}\times 30000=Rs.\,12000\] |
