Adam has stickers in 4 colours.
45 of the stickers are green.
The rest of the stickers are yellow, blue and red in the ratio of 2 : 4 : 5.
If there are 150 more blue stickers than yellow stickers,
how many green stickers are there?
Green |
Yellow |
Blue |
Red |
4 x 11 |
1 x 11 |
|
2 x 1 |
4 x 1 |
5 x 1 |
44 u |
2 u |
4 u |
5 u |
The number of green, yellow and blue stickers is the combined repeated identity.
Make the number of green, yellow and blue stickers the same using the LCM of 1 and 11.
LCM of 1 and 11 = 11
Number of more blue stickers than yellow stickers
= 4 u - 2 u
= 2 u
2 u = 150
1 u = 150 ÷ 2 = 75
Number of green stickers
= 44 u
= 44 x 75
= 3300
Answer(s): 3300
