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
5
7

12
Answer: Option
Explanation:

Let the number of cows be x and the number of hens be y.

Then, 4x + 2y = 2 (x + y) + 14 4x + 2y = 2x + 2y + 14 2x = 14 x = 7.

@Koushik.

No. of legs (4x + 2y).

Is 14 more (+14)? Than twice the no. of heads (2(x+y)).

@Monica.

As we know, the no of legs of a cow is 4 while the hen is of 2.

The number of cows was taken to be x and that of a hen be y.

Naturally, legs x heads = 4x (cow).

Legs x head = 2y (hen).
