Ivan had a total of 118 pomegranates and mangosteens. He sold
34 of the mangosteens and bought another 36 pomegranates. In the end, the number of pomegranates he had was
23 the number of mangosteens. How many more mangosteens than pomegranates did he have at first?

Pomegranates |
Mangosteens |
Total |
Before
|
2 u - 36
|
4x3 = 12 u |
118 |
Change |
+ 36 |
- 3x3 = 9 u |
|
After |
|
1x3 = 3 u |
|
Comparing between pomegranates and mangosteens |
2x1 = 2 u |
3x1 = 3 u |
|
The number of mangosteens in the end is repeated. Make the number of mangosteens in the end the same. LCM of 1 and 3 is 3.
Total number of pomegranates and mangosteens at first
= 2 u - 36 + 12 u
= 14 u - 36
14 u - 36 = 118
14 u = 118 + 36
14 u = 154
1 u = 154 ÷ 14 = 11
Number of more mangosteens than pomegranates at first
= 12 u - (2 u - 36)
= 12 u - 2 u + 36
= 10 u + 36
= 10 x 11 + 36
= 110 + 36
= 146
Answer(s): 146
