In a zoo, each pigeon has 2 legs, and each rabbit has 4 legs. The head count of the two species together is 12, and the leg count is How many pigeons and how many rabbits are there in the zoo?

A 6 & 3

B 5 & 10

C 8 & 4

D 6 & 8

Correct Answer: Option C

A/Q,

x + y = 12

or, 2x + 2y = 24 ....................... (1)

2x + 4y = 32 ............................ (2)

(2) - (1) we get,

2y = 8

or, y = 4 ......(3)

Now, from (1) and (3), we get,

x + 4 = 12

or, x = 12 - 4

or, x = 8
