If apples are bought at the rate of 30 for a rupee.

$\pink{ \bold{ \large { \huge{To \: Find :}}}}$

How many apples must be sold for a rupee so as to gain 20%.

$\red { \bold{ \large{ \huge{ Required \: Answer : \: 25}}}}$

$\green{ \bold{ \large{ \huge{SolutioN :}}}}$

The merchant makes a profit of 20%.

This means that the merchant sells 30 apples for Rs. 1.20.

Therefore, selling price of 1 apple = (1.20/30) = Rs.0.04.

The number of apples that can be sold for Rs. 1.00 = 1/0.04 = 25.

$\pink{ \bold{ \large{ \huge{The \: answer \: is \: 25.}}}}$

Answer 2

The merchant must sell 25 apples in order to gain a profit of 20%.

Given:

Apples are bought at the rate of 30 for a rupee

To Find:

The number of apples that must be sold in order to gain a profit of 20%.

Solution:

We have been given that the apples are bought at the rate of 30 for 1 rupee.

We need to find how many apples must the merchant sell in order to gain a profit of 20%. So for gaining a profit of 20% he must sell the 30 apples for Rs. 1.20 each.

Therefore, selling price of 1 apple = $(\frac{1.20}{30})$= Rs. 0.04

Hence, the number of apples that can be sold for Rs. 1.00 at 20% profit = $(\frac{1}{0.04})$ = 25

Therefore the merchant must sell 25 apples in order to gain a profit of 20%.
