please rate my answer if you find it helpful

Answer 2

Answer:

LION = 10

PARROT = 5

Step-by-step explanation:

SINCE LION AND PARROT HAS 4 AND 2 LEGS RESPECTIVELY

LET ' L ' BE LION AND ' P ' BE PARROT

TOTAL NO OF HEADS = 15

L + P = 15 --{1}

TOTAL NO OF LEGS = 50

4 L + 2 P = 50 --{2}

BY COMPARING {1} AND {2}, WE GET

{1}×-2 = -2L + -2P = -30

{2} = 4L + 2P = 50

――――----------------

2L = 20

L=10

SUBSTITUTE L =10 IN {1} WE GET,

10 + P =15

P = 15-5 = 5

HENCE , P=5 , L=10
