Question

First bunch of banana has $\frac{1}{4}$ more as many banana as a second bunch. If the second bunch has $3$ bananas less than the first bunch then the number of banana in first bunch is:

• A. $16$
• B. $15$
• C. $30$
• D. $22$

Answer 1

The correct option is B $15$

Let the no. of bananas in a second bunch $=x$
$\therefore$ No. of bananas in a first bunch $=x+\frac{x}{4}=\frac{5x}{4}$
As per question $\frac{5x}{4}-3=x$
$\Rightarrow 5x-12=4x$
$\therefore x=12$

Required no. of bananas in the first bunch
$=\frac{5\times 12}{4}=15$
