Pomegranates |
Passion fruits |
Before |
4x1 = 4 u |
1x1 = 1 u |
Change |
No change |
+ 10 |
After |
2x2 = 4 u |
3x2 = 6 u |
80% =
80100 =
45 40% =
40100 =
25 The number of pomegranates remains unchanged at first and in the end. Make the number of pomegranates the same. LCM of 4 and 2 is 4.
Number of passion fruits added
= 6 u - 1 u
= 5 u
5 u = 10
1 u = 10 ÷ 5 = 2
Number of pomegranates
= 4 u
= 4 x 2
= 8
Answer(s): 8
