Question

If a shopkeeper sells a pen for 80, he will incur a loss of 20. At what price should he sell it to make a profit if 20 ?​

Answer 1

He should sell it for Rs.120 to gain Rs. 20.

As he sells for Rs.80 he gets Rs. 20 loss .So 80 +20 =100

Now he don't have any loss.

But he want to gain Rs. 20 .So we add Rs. 20 to Rs. 100 to gain Rs. 20

Hence, answer is 120
