Adam has stickers in 4 colours.
27 of the stickers are yellow.
The rest of the stickers are red, green and blue in the ratio of 3 : 4 : 5.
If there are 50 more green stickers than red stickers,
how many yellow stickers are there?
Yellow |
Red |
Green |
Blue |
2 x 12 |
5 x 12 |
|
3 x 5 |
4 x 5 |
5 x 5 |
24 u |
15 u |
20 u |
25 u |
The number of yellow, red and green stickers is the combined repeated identity.
Make the number of yellow, red and green stickers the same using the LCM of 5 and 12.
LCM of 5 and 12 = 60
Number of more green stickers than red stickers
= 20 u - 15 u
= 5 u
5 u = 50
1 u = 50 ÷ 5 = 10
Number of yellow stickers
= 24 u
= 24 x 10
= 240
Answer(s): 240
