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

40

Step-by-step explanation:

Lets consider the total birds as x

x - (1/4x + 1/5x) = 22

x - 9/20x = 22

11/20x = 22

x = 22 × (20/11)

x = 40
