Answer 1

Answer: No. of tigers 29 and peacocks 18.

Step-by-step explanation:

Let the number of tigers be t and that of peacocks be p,

Then head count :

t+p =47 _____eq 1

Leg count :

4t+2p =152 _____eq 2

Solving eq 1 and eq 2 we get, t= 29

Substituting t =29 in eq 1, we get p = 18.

Therefore the number of tigers is 29 and peacocks is 18.

Answer 2

Answer:

The variety of tigers is 29 and peacocks is 18.

Step-by-step explanation:

Let the variety of tigers be T and that of peacocks be P,

Then head count :

T + P =47 ----------(1)

Leg count :

4T+2P =152 ----------------(2)

Solving equation(1) and equation(2)

we get, T = 29

Substituting T =29 in equation(1),

we get P = 18.

Therefore, the variety of tigers is 29 and peacocks is 18.
