Question
The ratio of the number of apples to that of oranges in a
basket is 3:5. If 15 more fruits of each type are added, the ratio becomes 6:9. Find the number of oranges in the basket originally.Solution
ATQ,
Let the original number of apples and oranges in the basket be ‘3x’ and ‘5x’, respectively.
ATQ;
(3x + 15) / (5x + 15) = (6/9)
Or, 9 × (3x + 15) = 6 × (5x + 15)
Or, 27x + 135 = 30x + 90
Or, 3x = 45
Or, x = 15
So, the number of oranges in the basket originally = 5 × 15 = 75
