Adam has stickers in 4 colours.
67 of the stickers are yellow.
The rest of the stickers are red, blue and green in the ratio of 1 : 4 : 3.
If there are 90 more blue stickers than red stickers,
how many yellow stickers are there?
Yellow |
Red |
Blue |
Green |
6 x 8 |
1 x 8 |
|
1 x 1 |
4 x 1 |
3 x 1 |
48 u |
1 u |
4 u |
3 u |
The number of yellow, red and blue stickers is the combined repeated identity.
Make the number of yellow, red and blue stickers the same using the LCM of 1 and 8.
LCM of 1 and 8 = 8
Number of more blue stickers than red stickers
= 4 u - 1 u
= 3 u
3 u = 90
1 u = 90 ÷ 3 = 30
Number of yellow stickers
= 48 u
= 48 x 30
= 1440
Answer(s): 1440
