Answer 1

Answer:

23 hens are there and 59 pigs is also there

Answer 2

There are 27 hens in Poultry farm

Solution:

Let H be the hens

Let P be the pigs

Each hen and pig has only one head.

Each hen has 2 legs and pig has 4 Legs

Rohan can see 84 heads and 282 legs

Total heads = 84

H + P = 84 ------ eqn 1

Total legs = 282

2H + 4P = 282 ------- eqn 2

Divide by 2

H + 2P = 141 -------- eqn 3

Subtract eqn 1 from eqn 3

H + 2P = 141

H + P = 84

( - ) -------------

P = 141 - 84

P = 57

Substitute P = 57 in eqn 1

H + 57 = 84

H = 84 - 57

H = 27

Thus there are 27 hens
