Answer 2

Answer:

10 lions and 5 parrots

Step-by-step explanation:

Let the number of lions be = x

and number of parrots be = y

ATQ,

x + y = 15...................(1)

4x + 2y = 50......................(2)

On solving these two equations we get,

2x = 20

x = 10

Hence there were 10 lions.

Then substituting x = 10 in (1), we get,

y = 5

Hence there were 10 lions and 5 parrots.
