In a basket,
13 are apples and the rest are starfruits. If I give away 12 starfruits, there will be
23 as many starfruits as apples. How many apples and starfruits are there in the basket altogether?
|
Apples |
Starfruits |
Total |
Before |
1x3 = 3 u |
2x3 = 6 u |
3x3 = 9 u |
Change |
|
- 12 |
|
After |
3x1 = 3 u |
2x1 = 2 u |
|
The number of apples remains unchanged.
Change in the number of starfruits
= 6 u - 2 u
= 4 u
4 u = 12
1 u = 12 ÷ 4 = 3
Number of apples and starfruits
= 9 u
= 9 x 3
= 27
Answer(s): 27
