Question
A seller marked an article 50% above its cost price and
sold it after allowing 10% discount. If he made a profit of Rs. 56, then find the difference between selling price and marked price of the article.Solution
Let the cost price of the article be Rs. β2xβ
So, marked price of the article = 2x Γ 1.5 = Rs. β3xβ
Selling price of the article = 3x Γ 0.9 = Rs. β2.7xβ
Profit = 2.7x β 2x = Rs. β0.7xβ
So, 0.7x = 56
β x = 80
Marked Price = 80 Γ 3 = Rs. 240
Selling Price = 80 Γ 2.7 = Rs. 216
Required difference = 240 β 216 = Rs. 24
