Question

a man asked how many hens and buffaleos he has .told that his animal have 120 eyes and 180 legs .how many hens and buffaloes has he have​

Answer 1

Answer:

30 buffaloes and 30 hens.

Step-by-step explanation:

Let there are x buffaloes and y hens.

Each animal have 2 eyes so

Total eyes = 2x+2y

120 = 2x + 2y

x+y=60............(1)

Each hen has two legs and each buffalo has four legs.

Total legs = 4x+2y

180=4x+2y

90=2x+y.............(2)

On subtracting equation (1) from equation (2).

2x+y=90

- x - y=-60

x= 30

y= 30

So, number of buffaloes and hens are 30 each

Answer 2

Answer:

40buffalo and 20hens

40buffalo =160leg and 80 eyes

20hens=40legs and 40eyes
