Adam has stickers in 4 colours.
34 of the stickers are blue.
The rest of the stickers are green, red and yellow in the ratio of 2 : 4 : 5.
If there are 30 more red stickers than green stickers,
how many blue stickers are there?
Blue |
Green |
Red |
Yellow |
3 x 11 |
1 x 11 |
|
2 x 1 |
4 x 1 |
5 x 1 |
33 u |
2 u |
4 u |
5 u |
The number of blue, green and red stickers is the combined repeated identity.
Make the number of blue, green and red stickers the same using the LCM of 1 and 11.
LCM of 1 and 11 = 11
Number of more red stickers than green stickers
= 4 u - 2 u
= 2 u
2 u = 30
1 u = 30 ÷ 2 = 15
Number of blue stickers
= 33 u
= 33 x 15
= 495
Answer(s): 495
