A fruit seller buys 700 oranges at the rate of ₹ 500 for 100 oranges and another variety of 500 oranges at the rate of ₹ 700 for 100 oranges and sells them at ₹ 84 per dozen. The profit percent is

Correct Answer: 20%

Explanation:

CP of 700 oranges = (500/100) x 700 = ₹ 3500
Total CP = 3500 + 3500 = 7000
And total number of oranges purchased = 700 + 500 = 1200
Total SP = (84/12 )x 1200 = ₹ 8400
∴ Profit percent = [(8400 - 7000)/7000]x100% = 20%
