Question

A men when asked ,how many hens and bufaaloes he has then he reply his animals has 180 legs and 120 eyes ,then how many hens he has

Answer 1

Hey dude.
Here's your answer...

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

Since each buffalo has 4 feet and each hen has 2 feet...

2x+4y = 180
x+2y = 90

Since both hens and buffaloes have 2 eyes...

2x+2y = 120
x+y = 60
x = 60-y

Substituting x's value in the first equation...

60-y+2y = 90
y = 30
x = 60-30
x = 30

So there are 30 hens and 30 buffaloes

Answer 2

There are 30 hens and 30 buffaloes
