Vaidev bought 66 more stickers than Cole and Cole bought 16 stickers more than Yoko. The total number of stickers Vaidev and Cole bought was 4 times the number of stickers Yoko bought.
- How many stickers does Vaidev need to give Cole so that they have the same number of stickers?
- How many stickers did all three of them have altogether?
Vaidev |
Cole |
Yoko |
1 u + 16 + 66 |
1 u + 16 |
1 u |
4 u |
1 u |
(a)
Number of stickers that Vaidev needs to give Cole so that they have same number of stickers
= 66 ÷ 2
= 33
(b)
Total number of stickers that Vaidev and Cole had
= 1 u + 16 + 66 + 1 u + 16
= 1 u + 1 u + 16 + 66 + 16
= 2 u + 98
4 u = 2 u + 98
4 u - 2 u = 98
2 u = 98
1 u = 98 ÷ 2 = 49
Total number of stickers that all three of them had
= 4 u + 1 u
= 5 u
= 5 x 49
= 245
Answer(s): (a) 33; (b) 245
