Question

In a cage, there are rabbits and parrots and the number of heads are 28 and feet are 72. Find the number of parrots and rabbits?

Answer 1

Given:

Number of heads = 28

Number of feet = 72

-

Assumed all parrots:

Number of feet = 28 x 2 = 56

-

Calculate the extra feet:

Extra feet = 72 - 56 = 16

-

Calculate the difference in feet between rabbits and parrots:

4 - 2 = 2

-

Find the number of rabbits:

Rabbits = 16 ÷ 2 = 8

-

Find the number of parrots:

Parrots = 28 - 8 = 20

-

Answer: Rabbits = 8, Parrots = 20

-

Check: (8 x 4)+ (20 x 2) = 72

Answer 2

let R=rAbbits
p=parrots
rabbits n parrots each have one head
so ur head equation be r+p=28

but rabbits have 4 feet n parrots have 2 so the feet equation be
4r+2p=72
2r+p=36 aftr dividing by 2
now subtract your head eqn from p equation so R=18
hence 18+p=28
p=10

R=18
P=10
