Question
A shopkeeper increased the price of an article by 50% over
its cost price. If the article is sold at a 10% discount, calculate the shopkeeper's gain percentage.Solution
ATQ,
Let the cost price of the article be Rs. '200z'
So, marked price = 200z * 1.5 = Rs. '300z'
So, selling price = 300z * 0.90 = Rs. '270z'
So, required gain percentage = {(270z - 200z)/200z} * 100 = 35%
