Adam has stickers in 4 colours.
35 of the stickers are yellow.
The rest of the stickers are red, blue and green in the ratio of 2 : 5 : 5.
If there are 150 more blue stickers than red stickers,
how many yellow stickers are there?
Yellow |
Red |
Blue |
Green |
3 x 6 |
2 x 6 |

2 x 1 |
5 x 1 |
5 x 1 |
18 u |
2 u |
5 u |
5 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 2 and 12.
LCM of 2 and 12 = 12
Number of more blue stickers than red stickers
= 5 u - 2 u
= 3 u
3 u = 150
1 u = 150 ÷ 3 = 50
Number of yellow stickers
= 18 u
= 18 x 50
= 900
Answer(s): 900
