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 $24$.
