Adam has stickers in 4 colours.
27 of the stickers are blue.
The rest of the stickers are red, yellow and green in the ratio of 1 : 3 : 6.
If there are 50 more yellow stickers than red stickers,
how many blue stickers are there?
Blue |
Red |
Yellow |
Green |
2 x 2 |
5 x 2 |
|
1 x 1 |
3 x 1 |
6 x 1 |
4 u |
1 u |
3 u |
6 u |
The number of blue, red and yellow stickers is the combined repeated identity.
Make the number of blue, red and yellow stickers the same using the LCM of 5 and 10.
LCM of 5 and 10 = 10
Number of more yellow stickers than red stickers
= 3 u - 1 u
= 2 u
2 u = 50
1 u = 50 ÷ 2 = 25
Number of blue stickers
= 4 u
= 4 x 25
= 100
Answer(s): 100
