Question

There are some boys and some cows in a garden if the number of their feet is 220 and the number of their heads is 60.the number of cows will be

Answer 1

Answer:

Let The Number of Boys Be "X"

Let The Number of Cows be "Y"

Feet Of Boys= 2×X

Feet of Cows=4×Y

therefore, According to Question

Total Head= Total Boys & Cows= X+Y= 60 (given)

Total Feet= 2X+4Y= 220.

= X+2Y=110.

On Substracting eg. 1 From eq. 2

X+2Y-(X+Y) =110-60

=> Y=50.

On Putting Y=50 in Equation. 1

X+Y=60

=>X= 10

Hence,

Total No. Of Boys= 10

Total No. Of Cows= 50
