The marked price of an article is 10/7 of the cost price and the selling price of that article is 4/5 of the marked price. What is the profit percentage?1). 17.24 2). 16.663). 14.28 4). 15.42

Answer»

Marked Price (MP) = (10/7) Cost Price (CP)----(1)

Selling Price (SP) = (4/5) Marked Price (MP)----(2)

SUBSTITUTING MP from EQUATION 1 in Equation 2, we get SP = (4/5) × (10/7) × CP = (8/7) CP

Profit PERCENTAGE = [(SP – CP)/CP] × 100 = [(8/7CP - CP)/CP] × 100 = (1/7) × 100 = 14.28%

∴ Required Percentage = 14.28%
