Question
Arjun purchased a mobile phone and marked its price 75%
higher than the cost price. He sold it after giving a 20% discount for Rs. 3600. What would be the selling price if a 10% discount was given instead?Solution
ATQ,
Let, cost price of the mobile phone be Rs. 100x
Marked price = 1.75 × 100x = Rs. 175x
Selling price after discount = 0.80 × 175x = Rs. 140x
According to the question:
140x = 3600
So, x = 25.71
Desired selling price = 0.90 × 1.75 × 2571 = Rs. 4042.65
