| A person sold an electronic watch at Rs. 96 in such a way that his percentage profit is same as the cost price of the watch. If he sells it at twice the percentage profit of its previous percentage profit, then the new selling price will be |
A) Rs. 132
B) Rs. 150
C) Rs. 192
D) Rs. 180
Correct Answer: A
Solution :
| Let the price of watch be Rs. x. |
| Then, \[SP=x+\frac{x\times x}{100}=96\] |
| \[\Rightarrow \] \[x=60\] |
| \[\therefore \] \[SP=60+\frac{60\times 120}{100}=\text{Rs}\text{. 132}\] |
