# Cost of 4 dozen bananas is Rs. 180. How many bananas can be purchased for Rs.90?

Given:

The cost of 4 dozen bananas is $Rs.\ 180$.

To do:

We have to find the number of bananas that can be purchased for $Rs.\ 90$.

To do:

The cost of 4 dozen bananas $= Rs.\ 180$

We know that,

1 dozen $=$ 12.

Therefore,

4 dozen bananas $= 4\times12$

$=48$

This implies,

The cost of 48 bananas $=Rs.\ 180$.

The number of bananas for Rs. 1 $=\frac{48}{180}$

Therefore,

The number of bananas for $Rs.\ 90$ $= \frac{48}{180}\times90$

$=24\ bananas$

The number of bananas that can be purchased for $Rs.\ 90$ is $24$.
