Question : 3
If the marked price of an article is 60% above the cost price. The article is sold at 25% discount. If the profit obtained is Rs. 40 then find the marked price of the article.
a) Rs. 320
b) Rs. 240
c) Rs. 200
d) Rs. 300
e) Rs. 360
Answer »Answer: (a)
Let the cost price = 100x, them
Marked price = 160x and Selling price = 160x – 25% of 160x = 160x – 40x = 120x
According to question
120x – 100x ≡ Rs. 40
20x ≡ Rs. 40
Hence, the marked price = 160x ≡ 20x × 8 = Rs. 40 × 8 = Rs. 320
