Simon bought 60 more stickers than Michael and Michael bought 26 stickers more than Marion. The total number of stickers Simon and Michael bought was 6 times the number of stickers Marion bought.
- How many stickers does Simon need to give Michael so that they have the same number of stickers?
- How many stickers did all three of them have altogether?
Simon |
Michael |
Marion |
1 u + 26 + 60 |
1 u + 26 |
1 u |
6 u |
1 u |
(a)
Number of stickers that Simon needs to give Michael so that they have same number of stickers
= 60 ÷ 2
= 30
(b)
Total number of stickers that Simon and Michael had
= 1 u + 26 + 60 + 1 u + 26
= 1 u + 1 u + 26 + 60 + 26
= 2 u + 112
6 u = 2 u + 112
6 u - 2 u = 112
4 u = 112
1 u = 112 ÷ 4 = 28
Total number of stickers that all three of them had
= 6 u + 1 u
= 7 u
= 7 x 28
= 196
Answer(s): (a) 30; (b) 196
