Pomegranates |
| Before |
4x1 =
4 u |
1x1 =
1 u |
| Change |
No change |
+ 15 |
| After |
2x2 =
4 u |
3x2 =
6 u |
80% =
80100 =
45 40% =
40100 =
25 The number of passion fruits remains unchanged at first and in the end. Make the number of passion fruits the same. LCM of 4 and 2 is 4.
Number of pomegranates added
= 6 u - 1 u
= 5 u
5 u = 15
1 u = 15 ÷ 5 = 3
Number of passion fruits
= 4 u
= 4 x 3
= 12
Answer(s): 12
