Question

The cost of $2$ dozen bananas is $Rs36$. How many bananas can be purchased with $Rs45$ ?

Answer 1

Let $x$ be the required bananas

Cost of $2$ dozen banana is $36$

$2$ dozen $=2\times 12=24$

$24$ bananas - $36$ Rs.

$x$ - $45$ Rs.

Taking cross-multiplication

$36\times x=24\times 45$

$x=\frac{24\times 45}{36}=30$

$30$ bananas purchased with $45$ rupees
