O 10%
11.11%
09.09%
12%
​

Answer 1

Step-by-step explanation:

let c.p of 1 mango Re 1.

then c.p of 18 mangoes= Rs 18

c.p of 20 mangoes Rs 20 = s.p of 18 mangoes

profit= s.p of 18 mangoes - c.p of 18 mangoes

=20 - 18

= 2

profit %= 2/18*100

=11.11 ans

Answer 2

The per cent profit made by the shopkeeper is 11.11%.

Given:

The purchase price of 20 mangoes=Selling prices of 18 mangoes

To find:

The per cent profit

Solution:

Let the purchase price of a mango be X.

We will obtain the purchase price of 18 mangoes and calculate the profit.

The purchase price of 18 mangoes=18×purchase prices of 1 mango

=18×X

=18X

Now, we know that the selling price of 18 mangoes=Purchase prices of 20 mangoes

So, the selling price of 18 mangoes=20×X

=20X

The amount of profit=Selling price of 18 mangoes-Purchase prices of 18 mangoes

=20X-18X

=2X

Now, the profit per cent=Amount of profit/Purchase price×100

Using the values,

=2X/18X×100

=1/9×100

=100/9

=11.11%

Therefore, the per cent profit made by the shopkeeper is 11.11%.
