Question
A shopkeeper marked an article x% above the cost price
and sold it after two consecutive discounts of 20% and 25%. Find the value of ‘x’, if in this transaction he had a loss of 7%.Solution
ATQ,
Let the cost price of the article be Rs. 100 Marked price of the article = 100 × {(100 + x)/100} = Rs. (100 + x) Selling price of the article = (100 + x) × 0.80 × 0.75 = (100 × 0.93) => 0.6(100 + x) = 93 => 60 + 0.6x = 93 => 0.6x = 33 => x = 55 So, the value of ‘x’ = 55%
