Question
The cost price and marked price of a pen are in the ratio
of 5:8. If the pen is sold with a 10% discount, the shopkeeper makes a profit of Rs. 100. Find the marked price of the pen.Solution
ATQ,
Let the cost price of the pen be Rs. ‘5x’ and the marked price be Rs. ‘8x’.
ATQ;
Selling price of the pen = 8x × 0.9 = Rs. ‘7.2x’
Profit = 7.2x – 5x = Rs. ‘2.2x’
So, 2.2x = 100
Or, x = 45.45
So, marked price of the pen = 8 × 45.45 = Rs. 364
