Two oranges, three bananas and four apples cost Rs. 15. Three oranges, two bananas and one apple cost Rs. 10. I bought 3 oranges, 3 bananas and 3 apples. How much did I pay?

Two oranges, three bananas and four apples cost Rs. 15. Three oranges, two bananas and one apple cost Rs. 10. I bought 3 oranges, 3 bananas and 3 apples. How much did I pay? Correct Answer Rs. 15

Calculation:

Let the number of oranges be O, bananas be B and apples be A.

Sentence I: 2O + 3B + 4A = Rs15

Sentence II: 3O + 2B + A = Rs 10

Adding I and II: 5O + 5B + 5A = Rs 25

Then, 3O + 3B + 3A = (25/5) × 3 = Rs 15

∴ The amount to be paid is Rs 15.
