Question

11. By selling a radio for Rs. 450, I would lose 10%. At what price should I sell it to gain 10%?​

Answer 1

Step-by-step explanation:

Given, S.P= 450

Lose =10 % of CP=

100 ÷ 10 CP

∴SP=90%ofCP=

90 ÷ 100 CP

90 ÷ 100 CP= 450 ⇒CP=160Rs.

For gaining 10 %

Profit= 10 ÷ 100 ×160=16Rs.

∴S.P=160+16= 176 RS.
