Marked price of an article is Rs. M, as it is marked by a certain price. Find the value of
M. Statement
I. If the shopkeeper gives a discount of 10%, so, there is a profit of 20%. If there is no discount offered there is a profit of Rs. 42. Statement
II. If the article is sold for a discount of 25%, there is a profit of Rs. 6. Statement
III. Marked up is 40%

Answer: C Statement I. 90% of MRP = 120% of CP MRP/CP = 120/90 = 4/3 If article is sold at MRP, then profit is Rs. 42 So, required MRP (M) = 4x * [42/ (4x – 3x)] = Rs. 168 This statement alone is sufficient to answer the question. It is clear that statement II, and III alone is not sufficient to answer the question. On combing (II + III) Let cost price of article = 100a 3 So MRP of article = 140a Selling price of article = 105a So, (105a – 100a) = Rs. 6 5a = Rs. 6 So, MRP of article = 6/5 x 140 = Rs. 168 Statement I alone or (II + III) is sufficient to answer the question. Hence answer is option C
