Question

one fourth 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 there in their nest​

Answer 1

Answer:Lets take the total number of birds= X

Therefore, Birds are at the riverbank =x/4

Birds are in the nest =x/5

Remaining birds wandering for food=22

According to the question,

=> x/4+x/5+22 =X

=>9x/20+22=X

=>9x+440=20x

=>11x =440

=>x =40

Total number of birds =40

Therefore birds in the nest =x/5

=40/5

=8

Answer 2

Answer:

Step-by-step explanation:

Total birds= 4/4 th part

In the river bank= 1/4 parts

In the nest = 1/5 parts

Wandering in search of food= 4/4 - ( 1/4 + 1/5)= 4/4 - 9/ 20

= 20/20 - 9/20

= 11/20 parts

11/ 20 parts = 22 birds .

1 /20 parts = 22/11 birds

20/20 parts = 2× 20= 40 birds

No birds in the nest = 1/5 of 40= 8 birds
