Eva had 35 less chocolate bars than Shiyun. Shiyun used

35 less |
| Before |
5x2 =
10 u |
3 u |
| Change |
- 4x2 =
- 8 u |
- 2 u |
| After |
1x2 =
2 u |
1 u |
Comparing Shiyun
and Parry in the end |
2 u |
1 u |
The number of chocolate bars that Shiyun had in the end is repeated. Make the number of chocolate bars that Shiyun had in the end the same. LCM of 1 and 2 is 2.
Number of chocolate bars that Eva had less than Shiyun
= 10 u - 3 u
= 7 u
7 u = 35
1 u = 35 ÷ 7 = 5
Number of chocolate bars that Shiyun had at first
= 10 u
= 10 x 5
= 50
Answer(s): 50
