Correct Answer: Rs. 160


Solution : Let the cost price be $x$
Gain = 5%
Selling Price = $\frac{105x}{100}$
New selling price = $\frac{105x}{100} - 12$
Now there is a loss of 2.5%
So, $x \times \frac{100-2.5}{100} = \frac{105x}{100} - 12$
⇒ $\frac{97.5x}{100} = \frac{105x}{100} - 12$
⇒ $97.5x = 105x - 1200$
⇒ $7.5x = 1200$
⇒ $x =160$
Hence, the correct answer is Rs. 160.
