Answer 1

Step-by-step explanation:

Given:

• One-fourth of birds of a flock are at a river bank and one-fifth of birds are in their nest. remaining 22 birds are wandering in search of food.

To Find:

• Number of birds in the nest.

Solution:

Let the total number of birds be x

Number of birds of a flock are at a river bank=x/5

Number of birds in the nest=x/4

Remaining=[x-{x/4+x/5)}

→x-9/20

→11/20

ACQ

→11x/20=22

→x=22×20/11

→x=40

Total number of birds=40

Number of birds in the nest=x/4

→40/4

→10 birds.
