In a basket,
12 are apples and the rest are starfruits. If I give away 20 starfruits, there will be
27 as many starfruits as apples. How many apples and starfruits are there in the basket altogether?
|
Apples |
Starfruits |
Total |
Before |
1x7 = 7 u |
1x7 = 7 u |
2x7 = 14 u |
Change |
|
- 20 |
|
After |
7x1 = 7 u |
2x1 = 2 u |
|
The number of apples remains unchanged.
Change in the number of starfruits
= 7 u - 2 u
= 5 u
5 u = 20
1 u = 20 ÷ 5 = 4
Number of apples and starfruits
= 14 u
= 14 x 4
= 56
Answer(s): 56
