In a basket,
12 are starfruits and the rest are oranges. If I give away 15 oranges, there will be
23 as many oranges as starfruits. How many starfruits and oranges are there in the basket altogether?
| |
Starfruits |
Oranges |
Total |
| Before |
1x3 =
3 u |
1x3 =
3 u |
2x3 =
6 u |
| Change |
|
- 15 |
|
| After |
3x1 =
3 u |
2x1 =
2 u |
|
The number of starfruits remains unchanged.
Change in the number of oranges
= 3 u - 2 u
= 1 u
1 u = 15
1 u = 15 ÷ 1 = 15
Number of starfruits and oranges
= 6 u
= 6 x 15
= 90
Answer(s): 90
