Zane and Mark share a bunch of pomegranates in the ratio 7 : 3. If Zane gives Mark 20 pomegranates from his share, they will have the same number of pomegranates. How many pomegranates does Zane have at first?

Before |
7 u |
3 u |
Change |
- 20 |
+ 20 |
After |
7 u - 20 |
3 u + 20 |
If Zane gives Mark 20 pomegranates from his share, they will have the same number of pomegranates.
7 u - 20 = 3 u + 20
7 u - 3 u = 20 + 20
4 u = 40
1 u = 40 ÷ 4 = 10
Number of pomegranates that Zane has
= 7 u
= 7 x 10
= 70
Answer(s): 70
