Adam has stickers in 4 colours.
57 of the stickers are yellow.
The rest of the stickers are blue, green and red in the ratio of 3 : 4 : 6.
If there are 120 more green stickers than blue stickers,
how many yellow stickers are there?
Yellow |
Blue |
Green |
Red |
5 x 13 |
2 x 13 |
|
3 x 2 |
4 x 2 |
6 x 2 |
65 u |
6 u |
8 u |
12 u |
The number of yellow, blue and green stickers is the combined repeated identity.
Make the number of yellow, blue and green stickers the same using the LCM of 2 and 13.
LCM of 2 and 13 = 26
Number of more green stickers than blue stickers
= 8 u - 6 u
= 2 u
2 u = 120
1 u = 120 ÷ 2 = 60
Number of yellow stickers
= 65 u
= 65 x 60
= 3900
Answer(s): 3900
