A man purchases a certain number of identical calculators at a rate of ₹1,200 per dozen. He sells them at ₹110 per piece. Find how many calculators he bought if his total profit is ₹360.
Show answer & explanation
Correct answer: C
Explanation
Given:
Cost price = ₹1200 per dozen
Selling price = ₹110 per calculator
Total profit = ₹360
By formula:
Profit = Total selling price − Total purchase price
Cost price per calculator = 1200/12 = 100
Profit per calculator = 110 − 100 = 10
Total calculators = 360/10 = 36
