| Before |
3x10 =
30 u |
8x10 =
80 u |
11x10 =
110 u |
| Change |
+ 3 u |
- 3 u |
|
| After |
3x11 =
33 u |
7x11 =
77 u |
10x11 =
110 u |
The total number of stickers that Paul and John had at first and in the end remains unchanged. Make the total number of stickers the same. LCM of 11 and 10 is 110.
Number of stickers that John gave Paul
= 33 u - 30 u
= 3 u
3 u = 24
1 u = 24 ÷ 3 = 8
Number of stickers that Paul had at first
= 30 u
= 30 x 8
= 240
Answer(s): 240
