Adam has stickers in 4 colours.
35 of the stickers are red.
The rest of the stickers are blue, green and yellow in the ratio of 2 : 3 : 6.
If there are 100 more green stickers than blue stickers,
how many red stickers are there?
Red |
Blue |
Green |
Yellow |
3 x 11 |
2 x 11 |
|
2 x 2 |
3 x 2 |
6 x 2 |
33 u |
4 u |
6 u |
12 u |
The number of red, blue and green stickers is the combined repeated identity.
Make the number of red, blue and green stickers the same using the LCM of 2 and 11.
LCM of 2 and 11 = 22
Number of more green stickers than blue stickers
= 6 u - 4 u
= 2 u
2 u = 100
1 u = 100 ÷ 2 = 50
Number of red stickers
= 33 u
= 33 x 50
= 1650
Answer(s): 1650
