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
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

Let,
R=X, P=(12-X)
A/Q,
4X + 2(12 - X) = 32
4X + 24 - 2X = 32
2X = 8
X = 4
Rabbit = 4
pigeon =(12-X)=12-4=8
P=8, R=4
