Question

Pal has some hens and goats if the number of their heads are 43 and the number of feet are 142, what will be the number of hens?​

Answer 1

Answer:

Let no of hens = x

No of goats = 43-x ( total heads of animals = 43 given, So we assume it as total animals)

Now hens have 2 legs & goats have 4 legs

Total no of legs =142 (given)

I.e 2x + 4(43-x)=142

2x+172-4x=142

172-2x=142

172-142=2x

30=2x

30/2=x

15=x

& X = hen = 15.
