Question

If a man were to sell his T.V set for Rs. 7200, he would have lost 25%. For what price must he sell it to gain 25%?

Answer 1

CP = 7200

25% of 7200 = 7200*25/100 = Rs . 1800

So, SP = 7200-1800 = Rs. 5400

25% of 5400 = 5400*25/100 = 1350

So, New SP = 5400+1350 = Rs. 6750

Answer 2

25%of 7200 is 1800 i.e. cost price of tv was 9000. now 25% of 9000 is 2250 . so shop keeper should sell it for 11250
