Explanation
Four milkmen rented a pasture
- A grazed 24 cows for 3 months
- B grazed 10 cows for 5 months
- C grazed 35 cows for 4 months
- And D grazed 21 cows for 3 months
Firs we’ll calculate the total share ratio of A, B, C and D by multiplying 24 with 3, 10 with 5, 35 with 4 and 21 with 3 respectively.
Now by substituting A’s share of rent (720), As, share ratio (72) and total ratio (325) in the formula mentioned below;
A’s share of rent = (A’s share ratio x total rent) / total ratio
It gives total rent Rs. 3250.
To Find
Total rent = ?
Solution
Let suppose; total rent = y
Total ratio of A, B, C and D = 24 x 3 : 10 x 5 : 35 x 4 : 21 x 3
A : B : C : D = 72 : 50 : 140 : 63 (and 72 + 50 + 140 + 63 = 325)
A’s share of rent = (A’s share ratio x total rent) / total ratio
720 = (72 x y)/325
720 x 325 = 72 x y
234000 = 72 x y
234000/72 = y
y = Rs. 3250 answer
Conclusion
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 then total rent of the field will be Rs. 3250.
