A shepherd uses a field to graze 20 cows and 60 sheep. A cow grazes four times
the grass a sheep grazes. 15 cows and 20 sheep are owned by A and the remaining
by B, if the charges of the pasture are Rs.K, nearly how much does A have to bear?
A) 57%
B) 51%
C) 52%
D) None of these​

Answer 1

Answer:

i think your answer is (A)57%

Answer 2

Answer:

A - 15 cows and 20 sheeps

1 cow grazes 4 times of sheep so that,

15×4 + 20= 60+20=80

B - 5 cows and 40 sheeps

5×4+40= 20+40=60

Lets A:B= 80:60=4:3

Assume k is 1 and

4x + 3x = 1

7x = 1

x= 1/7

A's share is 4x i.e 4 ×1/7= 0.57

lets convert into percentage 0.57× 100 = 57%
