Nirmala gains 10% by selling her bicycle for a certain price. If she sells it at 2 times the price, the percentage of profit will be :
Solution: Let C.P =Rs. x. then, S.P. = Rs. (110% of x) = Rs. 11x/10.
New S.P. = Rs. (2*11x/10) =Rs. 22x/10. profit = Rs. (22x/10 - x) = Rs. 6x/5.
.'. Profit% = (6x/5 *1/x * 100) = 120%.
