Adam has stickers in 4 colours.
58 of the stickers are blue.
The rest of the stickers are red, green and yellow in the ratio of 1 : 3 : 5.
If there are 150 more green stickers than red stickers,
how many blue stickers are there?
Blue |
Red |

Yellow |
5 x 3 |
3 x 3 |

1 x 1 |
3 x 1 |
5 x 1 |
15 u |
1 u |
3 u |
5 u |
The number of blue, red and green stickers is the combined repeated identity.
Make the number of blue, red and green stickers the same using the LCM of 3 and 9.
LCM of 3 and 9 = 9
Number of more green stickers than red stickers
= 3 u - 1 u
= 2 u
2 u = 150
1 u = 150 ÷ 2 = 75
Number of blue stickers
= 15 u
= 15 x 75
= 1125
Answer(s): 1125
