Question

In a zoo, the numbers of monkeys, parrots and snakes are in ratio of 7:13:5. If the total number of monkeys, parrots and snakes is 125, then how many parrots are there?

Answer 1

Number of parrots are 65 .

Explanation:

As given

In a zoo, the numbers of monkeys, parrots and snakes are in ratio of 7:13:5.

If the total number of monkeys, parrots and snakes is 125.

Let us assume that x be the scalar multiple .

Thus

Number of monkeys = 7x

Number of parrots = 13x

Number of snakes = 5x

Thus the equtaion becomes

7x + 13x + 5x = 125

25x = 125

`x = (125)/(25)`

x = 5

Thus

Number of parrots = 13x

= 13 × 5

= 65

Therefore the number of parrots are 65 .
