Adam has stickers in 4 colours.
27 of the stickers are blue.
The rest of the stickers are green, red and yellow in the ratio of 2 : 3 : 3.
If there are 50 more red stickers than green stickers,
how many blue stickers are there?
Blue |
Green |
Red |
Yellow |
2 x 8 |
5 x 8 |
|
2 x 5 |
3 x 5 |
3 x 5 |
16 u |
10 u |
15 u |
15 u |
The number of blue, green and red stickers is the combined repeated identity.
Make the number of blue, green and red stickers the same using the LCM of 5 and 8.
LCM of 5 and 8 = 40
Number of more red stickers than green stickers
= 15 u - 10 u
= 5 u
5 u = 50
1 u = 50 ÷ 5 = 10
Number of blue stickers
= 16 u
= 16 x 10
= 160
Answer(s): 160
