Question

One-fourth of birds of a flock are at a river
bank and one-fifth of that flock are in their
nest. Remaining 22 birds are wandering in
search of food. What is the number of birds
which are in their nest?
​

Answer 1

The number of birds in the nest is 8.

Step-by-step explanation:

Let the number of birds in the nest = x

Than, one fourth of birds are flock at river = x/4

One fifth are in nest = x/5

Remaining birds  =  22

Solution:

x/4 +x/5+22 =x

5x +  4x + 440 = 20x

440 = 11 x

x = 40

Total number of birds =40

The number of birds in nest=40/5=8

Hence the number of birds in the nest is 8.
