A shopkeeper marks the price of an article at Rs. 320. Find the cost price if after allowing a discount of 10%, he still gains 20% on the cost price.
Let the cost price be x.
A/c to question , after allowing a discount of 10%, he still gains 20% on the cost price .
$$\frac{90}{100} \times marked price = \frac{120}{100} \times cost price$$
$$\frac{90}{100} \times 320 = \frac{120}{100} \times x$$
x = 240
So, the answer would be option a)Rs. 240
