Adam has stickers in 4 colours.
27 of the stickers are green.
The rest of the stickers are blue, yellow and red in the ratio of 4 : 5 : 3.
If there are 130 more yellow stickers than blue stickers,
how many green stickers are there?
Green |
Blue |
Yellow |
Red |
2 x 12 |
5 x 12 |
|
4 x 5 |
5 x 5 |
3 x 5 |
24 u |
20 u |
25 u |
15 u |
The number of green, blue and yellow stickers is the combined repeated identity.
Make the number of green, blue and yellow stickers the same using the LCM of 5 and 12.
LCM of 5 and 12 = 60
Number of more yellow stickers than blue stickers
= 25 u - 20 u
= 5 u
5 u = 130
1 u = 130 ÷ 5 = 26
Number of green stickers
= 24 u
= 24 x 26
= 624
Answer(s): 624
