In a group of cows and hens, the number of legs are 14 more than twice the number of heads. The number of cows is :

a. 5
b. 7
c. 10
d. 12

Read Solution (Total 2)

Ans is (b)7
Let no of cows be x, no of hens be y.
So heads=x+y
Legs=4x+2y
Now, 4x+2y = 2(x+y)+ 14
2x = 14
x = 7.

Legs=14+2*no. Of heads
Let X=cow heads
Y=hens heads
L=14+2(X+y)
Y=0
