| Four milkmen rented a pasture. A grazed 18 cows for 4 months, B grazed 25 cows for 2 months, C grazed 28 cows for 5 months and D grazed 21 cows for 3 months. If As share of rent is Rs. 720, then what will be the total rent of the pasture? |
A) Rs. 1650
B) Rs. 3250
C) Rs. 3500
D) Rs. 3000
Correct Answer: B
Solution :
| Ratio of rents of A, B, C and D |
| \[=(18\times 4):(25\times 2):(28\times 5):(21\times 3)\] |
| \[=72:50:140:63\] |
| Let the total rent be x. |
| Then, As share \[=\frac{72x}{(72+50+140+63)}=\frac{72x}{325}\] |
| According to the question, |
| \[\frac{72x}{325}=720\]\[\Rightarrow \]\[x=\frac{720\times 325}{72}\] |
| \[\therefore \] Total rent = Rs. 3250 |
