Question

by selling 50 bananas a vendor gains the selling price of 10 bananas. Find his gain or lost percent

Answer 1

Let sp of each banana=1rs

So sp of 50 bananas =50rs

Gain=sp of 10 bananas=10rs

So cp = sp-gain

Cp =40rs

Gain%=gain *100/cp

=10*100/40

=25%

Answer 2

Gain percentage be selling 50 bananas is 25%.

• By selling 50 bananas a vendor gains the selling price of 10 bananas.

• Let us consider the selling price of 1 banana be x.

• Selling price of 50 bananas = 50x and gain is 10x.

• Now cost price of 50 bananas is Selling price - Gain = 50x - 10x = 40x.

• We have to find the gain percentage or loss percentage.

• As the vendor gains selling price of 10 bananas, he gains a profit.

• Gain percentage = $\frac{Gain}{Cost price}$ × 100

Gain percentage = $\frac{10x}{40x}$ × 100  

Gain percentage = $\frac{1}{4}$ × 100

Gain percentage = 25%.
