Dear Student,
◆ Answer -
8 birds
● Explanation -
Let x be total no of birds in flock.
Birds at riverbank are x/4. Birds in the nest are x/5.
Remaining 22 birds are searching for food.
Birds searching for food = x - x/4 - x/5
22 = 11x/20
x = 22 × 20/11
x = 40 birds
Hence, birds in the nest are x/5 = 40/5 = 8 birds.
Hence, 8 birds are in the nest.
Thanks dear. Hope this helps you...
