Adam has stickers in 4 colours.
89 of the stickers are red.
The rest of the stickers are green, yellow and blue in the ratio of 1 : 3 : 4.
If there are 60 more yellow stickers than green stickers,
how many red stickers are there?
Red |
Green |
Yellow |
Blue |
8 x 8 |
1 x 8 |

1 x 1 |
3 x 1 |
4 x 1 |
64 u |
1 u |
3 u |
4 u |
The number of red, green and yellow stickers is the combined repeated identity.
Make the number of red, green and yellow stickers the same using the LCM of 1 and 8.
LCM of 1 and 8 = 8
Number of more yellow stickers than green stickers
= 3 u - 1 u
= 2 u
2 u = 60
1 u = 60 ÷ 2 = 30
Number of red stickers
= 64 u
= 64 x 30
= 1920
Answer(s): 1920
