Upper primary school mathematics question UPQ297
Fatimah prepared 2 baskets of fruits to serve the guests during Hari Raya Puasa. Each basket contained apples and oranges. The ratio of the number of apples to the number of oranges in Basket A was 5 : 4. In Basket B, the number of oranges was 2/5 of the number of apples. Fatimah transferred half of the oranges from Basket A to Basket B. In the end, the total number of fruits in Basket A became 105 and the ratio of the number of apples to the number of oranges in Basket B became 7 : 4.
(a) How many oranges were transferred from Basket A to Basket B?
(b) How many fruits were there in Basket B in the end?
Ratio of fruit in Basket A at first, apples : oranges = 5 : 4
Half of oranges transfer to Basket B and the total number of fruits in Basket A left are 105
The Fraction Model
From the model
Ratio in Basket A, apples : oranges = 5 : 2
7 units = 105
1 unit = 15
The number of oranges transfer from Basket A to Basket B = 2 × 15 = 30
In Basket B, the number of oranges was 2/5 of the number of apples at first
Ratio in Basket B at first, apples : oranges = 5 : 2 = 35 : 14
After 30 oranges transfer to Basket B
The Ratio in Basket B, apples : oranges = 7 : 4 = 35 : 20
The different in number of oranges = 6 units = 30
1 unit = 5
The number of fruits in Basket B at the end = 55 × 5 = 275
