Correct Answer - Option 4 : 20 kg
Given:
A fruit seller Kishan buys bananas at 3 kg for Rs. 9
Kishan sells banana at 5 kg for Rs. 40.
Formula used:
Profit = Selling Price – Cost Price
Calculations:
Cost price of 1 kg Banana = 9/3 = Rs. 3
Selling price of 1 kg Banana = 40/5 = Rs. 8
Profit earned by selling 1 kg banana = 8 – 3 = Rs. 5
For earning Rs. 100, he must sell = 100/5 = 20 kg
∴ For earning Rs. 100, Kishan must sell 20 kg.
