Answer 2

Answer:

The cost price of the lamp will be Rs. 350.

Explanation:

The selling price of the lamp is given by Rs. 315 while the loss percent is given as 10%.

Let us assume that the cost price of the lamp is Rs. x. Then we can say that the difference between the cost price and the selling price will be equal to the loss incurred:

x - Rs. 315 = 10% of x

x - 315 = 0.1x

x - 0.1x = 315

0.9x = 315

$x = \frac{315}{0.9}$

x = Rs. 350

Thus the cost price of the lamp will be Rs. 350.
