A shopkeeper gains 17% after allowing a discount of 10% on the marked price of an article. Find his profit percent if the article is sold at marked price allowing no discount.

A) 0.3

B) 0.37

C) 0.23

D) 0.27

Correct answer:
A) 0.3

Description for Correct answer:
Let the cost price = Rs.100

Therefore, Selling price = \( 100 \times \frac{117}{100} = Rs.117 \)

Therefore, Marked price = \( 117 \times \frac{100}{90} = 130 \)

Therefore, Profit Percentage = \( \frac{ \left(130-100\right) }{100} \times 100 = 30\% \)
