Question
A trader allows a discount of 18% on the marked price of
an article. How much percentage above the cost price must he mark it so as to get a profit of 6.6%?Solution
Let the Cost price of the article be Rs. 100, then SP of the article = 100 × (106.6) = Rs. 106.6 MP of the article = 106.6 × (100/82) = 130 MP is more than CP by = 130 – 100 = 30 ∴ MP is more than CP by (in %) = 30/100 × 100 = 30%
