Number of birds in the nest will be 8

Step-by-step explanation:

Let the total number of bird is x

It is given that \frac{1}{4} of the bird are at river bank

So number of bird at river bank =x\times \frac{1}{4}=\frac{x}{4}

\frac{1}{5} of total bird are in the nest

So number of bird in the nest is equal to x\times \frac{1}{5}=\frac{x}{5}

So number of birds at bank river and in the nest =\frac{x}{5}+\frac{x}{4}=\frac{9x}{20}

So number of bird left =x-\frac{9x}{20}=\frac{11x}{20}

According to question

\frac{11x}{20}=22

x = 40

So number of bird in the nest is \frac{1}{5}\times 40=8

So there are 8 birds in the nest
