Four milkmen rented a pasture. A grazed 24 cows for 3 months; B 10 cows for 5 months; C 35 cows for 4 months and D 21 cows for 3 months. If A's share of rent is Rs. 720, find the total rent of the field.

Answer:

Explanation:

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 total rent be Rs. $x$.

Then, A's share = Rs. $\frac{72x}{325}$.

$\frac{72x}{325}$ $= 720$.

$x=\frac{720\times 325}{72}$ $= 3250$.

Hence, total rent of the field is Rs. 3250.
