Adam has stickers in 4 colours.
35 of the stickers are yellow.
The rest of the stickers are blue, red and green in the ratio of 3 : 4 : 4.
If there are 110 more red stickers than blue stickers,
how many yellow stickers are there?
Yellow |
Blue |
Red |
Green |
3 x 11 |
2 x 11 |
|
3 x 2 |
4 x 2 |
4 x 2 |
33 u |
6 u |
8 u |
8 u |
The number of yellow, blue and red stickers is the combined repeated identity.
Make the number of yellow, blue and red stickers the same using the LCM of 2 and 11.
LCM of 2 and 11 = 22
Number of more red stickers than blue stickers
= 8 u - 6 u
= 2 u
2 u = 110
1 u = 110 ÷ 2 = 55
Number of yellow stickers
= 33 u
= 33 x 55
= 1815
Answer(s): 1815
