| Four milkmen rented a pasture. A grazed 24 cows for 3 months; B grazed 10 cows for 6 months; C grazed 35 cows for 4 months and D grazed 21 cows for 3 months. If A's share of rent is Rs. 720, then the total rent of the field |
A) Rs. 3340
B) Rs. 3250
C) Rs. 3350
D) Rs. 3450
Correct Answer: B
Solution :
| Ratio of shares of A, B, C, D |
| \[=(24\times 3):(10\times 5):(35\times 4):(21\times 3)\] |
| = 72: 50: 140: 63 |
| Let the total rent be Rs. x |
| Then, As share \[=\text{Rs}\text{.}\frac{72x}{325}\] |
| \[\therefore \] \[\frac{72x}{325}=720\] |
| \[\Rightarrow \] \[x=3250\] |
