Question

3 oranges & 2apples. Cost 22. If price of orange increase by 25% & that of apple inceease by 20% then 2 oranges & 3 apples cost 28. Find out the actual price of an apple

Answer 1

Let cost of an orange X and the cost of an apple is Y.Then,
Total cost of 3 oranges and 2 apples= 3 × X + 2 × Y
=> 22 = 3X + 2Y -----(1)
Now, after increase of 25% in price of one orange it cost X × 125% = 1.25X
And the cost of an apple become Y × 120 % = =1.2Y.
=> Now, Total cost of 2 oranges and 3 apples = 1.25X × 2 + 1.2Y × 3
=> 28 = 2.5X + 3.6Y -----(2)
Now, on solving equation (1) & (2) , we get
=> [ (2) × 3 - (1) × 2.5 ]
=> Y = 5
Hence, actual price of an apple is Rs. 5

Answer 2
