Adam has stickers in 4 colours.
59 of the stickers are yellow.
The rest of the stickers are green, blue and red in the ratio of 1 : 4 : 3.
If there are 60 more blue stickers than green stickers,
how many yellow stickers are there?
Yellow |
Green |
Blue |
Red |
5 x 2 |
4 x 2 |
|
1 x 1 |
4 x 1 |
3 x 1 |
10 u |
1 u |
4 u |
3 u |
The number of yellow, green and blue stickers is the combined repeated identity.
Make the number of yellow, green and blue stickers the same using the LCM of 4 and 8.
LCM of 4 and 8 = 8
Number of more blue stickers than green stickers
= 4 u - 1 u
= 3 u
3 u = 60
1 u = 60 ÷ 3 = 20
Number of yellow stickers
= 10 u
= 10 x 20
= 200
Answer(s): 200
