Question

In a zoo there are some lions and parrot of the number of legs is 6 less than 4 times the number of heads

Answer 1

Let the number of lions be 'x' and number of parrots be 'y'

total number of heads = x+y

total numbers of legs = 4x + 2y

So, according to the question

4x + 2y = 4(x + y) - 6

⇒ 4x + 2y = 4x + 4y - 6

⇒ y = 3

the number of parrots (y) = 3
