Adam has stickers in 4 colours.
45 of the stickers are blue.
The rest of the stickers are yellow, green and red in the ratio of 1 : 3 : 6.
If there are 10 more green stickers than yellow stickers,
how many blue stickers are there?
Blue |
Yellow |
Green |
Red |
4 x 10 |
1 x 10 |
|
1 x 1 |
3 x 1 |
6 x 1 |
40 u |
1 u |
3 u |
6 u |
The number of blue, yellow and green stickers is the combined repeated identity.
Make the number of blue, yellow and green stickers the same using the LCM of 1 and 10.
LCM of 1 and 10 = 10
Number of more green stickers than yellow stickers
= 3 u - 1 u
= 2 u
2 u = 10
1 u = 10 ÷ 2 = 5
Number of blue stickers
= 40 u
= 40 x 5
= 200
Answer(s): 200
