Adam has stickers in 4 colours.
59 of the stickers are yellow.
The rest of the stickers are green, red and blue in the ratio of 3 : 4 : 3.
If there are 80 more red stickers than green stickers,
how many yellow stickers are there?
Yellow |
Green |
Red |
Blue |
5 x 5 |
4 x 5 |
|
3 x 2 |
4 x 2 |
3 x 2 |
25 u |
6 u |
8 u |
6 u |
The number of yellow, green and red stickers is the combined repeated identity.
Make the number of yellow, green and red stickers the same using the LCM of 4 and 10.
LCM of 4 and 10 = 20
Number of more red stickers than green stickers
= 8 u - 6 u
= 2 u
2 u = 80
1 u = 80 ÷ 2 = 40
Number of yellow stickers
= 25 u
= 25 x 40
= 1000
Answer(s): 1000
