Question

2. A friend of mine bought a used pressure cooker for Rs 60. She somehow did not
find it useful and so when a friend of hers offered her Rs 70 she sold it to her.
However, she felt bad after selling it and decided to buy it back from her friend by
offering her Rs 80. After having bought it once again she felt that she did not really
need the cooker. So she sold it at the auction for Rs 90.
How much profit did she make? Did she at all make any profit?

Answer 2

Given:

The original cost price of the cooker= Rs.60

The price of the cooker when sold in auction=Rs.90

To find:

The amount of profit

Solution:

Yes, she made a profit of Rs. 20.

We can find the amount by following the steps given below-

We know that profit is the difference between the cost price and the selling price. It is obtained when the selling price is greater than the cost price.

Profit=Selling price - cost price

In case 1, she bought the cooker at the cost price of Rs. 60. She sold it to her friend for Rs.70.

Here, selling price > cost price so there is a profit.

Profit= 70-60

=Rs.10

In case 2, she sold it for Rs.70 but bought it back for Rs.80. This is a case of loss.

In case 3, she bought it for Rs.80 and sold it in the auction for Rs.90.

Here again the selling price > cost price.

Profit= 90-80

= Rs.10

So, the total profit earned by her= Profit in case 1+profit in case 3

=10+10

= Rs.20

Therefore, she made a profit of Rs.20.
