Adam has stickers in 4 colours.
49 of the stickers are yellow.
The rest of the stickers are red, green and blue in the ratio of 4 : 5 : 8.
If there are 110 more green stickers than red stickers,
how many yellow stickers are there?
Yellow |
Red |
Green |
Blue |
4 x 17 |
5 x 17 |
|
4 x 5 |
5 x 5 |
8 x 5 |
68 u |
20 u |
25 u |
40 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 17.
LCM of 5 and 17 = 85
Number of more green stickers than red stickers
= 25 u - 20 u
= 5 u
5 u = 110
1 u = 110 ÷ 5 = 22
Number of yellow stickers
= 68 u
= 68 x 22
= 1496
Answer(s): 1496
