Adam has stickers in 4 colours.
38 of the stickers are blue.
The rest of the stickers are green, yellow and red in the ratio of 3 : 5 : 3.
If there are 130 more yellow stickers than green stickers,
how many blue stickers are there?
Blue |
Green |
Yellow |
Red |
3 x 11 |
5 x 11 |

3 x 5 |
5 x 5 |
3 x 5 |
33 u |
15 u |
25 u |
15 u |
The number of blue, green and yellow stickers is the combined repeated identity.
Make the number of blue, green and yellow stickers the same using the LCM of 5 and 11.
LCM of 5 and 11 = 55
Number of more yellow stickers than green stickers
= 25 u - 15 u
= 10 u
10 u = 130
1 u = 130 ÷ 10 = 13
Number of blue stickers
= 33 u
= 33 x 13
= 429
Answer(s): 429
