Question

By selling a watch for rs.1275, Javed lost 15%. at what price should he sell to make a profit of 10%

Answer 1

Let CP be x
SP = Rs.1275
Then CP is,
=> x - (x × 15/100) = 1275
=> x - 15x/100 = 1275
=> 85x = 127500
=> x = 127500/85 = 1500
If he sells at 10% profit,
1500 + (1500×10%) = 1500+150 = 1650.
Answer. He should sell the watch at Rs.1650

Hope it helps !!!
