Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. ₹780.
Calculations:
Selling price of 40 dozen bananas = 1440
Gain = 20%
Cost price of 40 dozen bananas = 1440/1.2 = 1200
Cost price of 20 dozen bananas = 1200/2 = 600
Selling price of 20 dozen bananas after gaining 30% profit = 600 × 1.3 = 780
