Q21 of 90 Page 133

Sandeep sold a television at a loss of 8%. If he had sold it for Rs. 3360 more, he would have gained 6%. For how much did Sandeep buy it?

Let’s suppose CP of TV be Rs. x


He sold TV by the loss of 8%



He sold TV by gain of 6%



So, according to the question,



x + 0.6x – x + 0.8x = 3600


0.14x = 3600


x = Rs. 24000


Hence, Cost Price of TV = Rs. 24,000.
