Question
The selling price of a product when it is sold at a profit
of 10% is Rs. 40 more than its selling price when it is sold at a loss of 25%. What would be the selling price of the product if it is sold at a profit of 20%?Solution
ATQ,
Let the cost price of the product = Rs. '100y'
According to the question,
100y × 1.10 - 100y × 0.75 = 40
Or, 110y - 75y = 35y = 40
So, y = (40/35) = 1.14
Cost price of the product = 1.14 × 100 = Rs. 114
Required selling price = 114 × 1.20 = Rs. 136.80
