In a basket,
12 are kiwis and the rest are apples. If I give away 15 apples, there will be
27 as many apples as kiwis. How many kiwis and apples are there in the basket altogether?
|
Kiwis |
Apples |
Total |
Before |
1x7 = 7 u |
1x7 = 7 u |
2x7 = 14 u |
Change |
|
- 15 |
|
After |
7x1 = 7 u |
2x1 = 2 u |
|
The number of kiwis remains unchanged.
Change in the number of apples
= 7 u - 2 u
= 5 u
5 u = 15
1 u = 15 ÷ 5 = 3
Number of kiwis and apples
= 14 u
= 14 x 3
= 42
Answer(s): 42
