Question
A shopkeeper marked an item 50% above its cost and offered
a 30% discount. If the item is sold at Rs. 3,150, then what is the profit?Solution
ATQ,
Let the cost price of article be Rs. '100b'
Marked price of article = 1.50 × 100b = Rs. '150b'
Selling price of article = 0.70 × 150b = Rs. '105b'
So, 105b = 3,150
Or, 'b' = 30
Therefore, required profit = 5 × 30 = Rs. 150
