Question

25. The average price of 3 Mangoes and 2 apples is Rs.8. The average price of 3
Apples and 3 Oranges is Rs.4.50. The average price of 3 Mangoes and 3 Oranges is
Rs.7. What is the price of 1 Mango?​

Answer 1

3 mangoes + 2 apples = ₹8

3 mangoes = ₹8 - 2 apples-----(i)

3 oranges + 3 apples = ₹4.5

3 oranges = ₹4.5 - 3 apples-----(ii)

3 mangoes + 3 oranges = ₹7

Putting the values of eqn.(i) and (ii),

₹8 - 2 apples + ₹4.5 - 3 apples = ₹7

₹12.5 - ₹7 = 5 apples

5 apples = ₹5.5

1 apple = ₹1.1

Putting this value in equation (i),

3 mangoes = ₹8 - 2 × ₹1.1

3 mangoes = ₹8 - ₹2.2

3 mangoes = ₹5.8

1 mango = ₹1.93
