| Before |
1x3 =
3 u |
4x3 =
12 u |
| Change |
No change |
- 20 |
| After |
3x1 =
3 u |
2x1 =
2 u |
20% =
20100 =
15 60% =
60100 =
35 The number of passion fruits remains unchanged at first and in the end. Make the number of passion fruits the same. LCM of 3 and 1 is 3.
Number of pomegranates removed
= 12 u - 2 u
= 10 u
10 u = 20
1 u = 20 ÷ 10 = 2
Number of pomegranates
= 12 u
= 12 x 2
= 24
Answer(s): 24
