Answer 1

His gain% is 56.25%

Step-by-step explanation:

Cost Price of 15 bananas = Rs 12

Selling price of 12 bananas = Rs 15

So Selling price of 15 bananas = $\frac{15\times 15}{12}=Rs18.75$

Since the Selling Price is greater than the Cost price, it is a Gain.

We know that

$Gain \%=\frac{Selling Price-Cost Price}{Cost Price} \times 100$

Plugging the known values:

$Gain \%=\frac{18.75-12}{12} \times 100\\\\\Rightarrow Gain \%=\frac{18.75-12}{12} \times 100\\\\\Rightarrow Gain \%=0.5625 \times 100\\\\\Rightarrow Gain \%=56.25\%$
