Adam has stickers in 4 colours.
78 of the stickers are blue.
The rest of the stickers are green, yellow and red in the ratio of 1 : 4 : 9.
If there are 60 more yellow stickers than green stickers,
how many blue stickers are there?
Blue |
Green |
Yellow |
Red |
7 x 14 |
1 x 14 |
|
1 x 1 |
4 x 1 |
9 x 1 |
98 u |
1 u |
4 u |
9 u |
The number of blue, green and yellow stickers is the combined repeated identity.
Make the number of blue, green and yellow stickers the same using the LCM of 1 and 14.
LCM of 1 and 14 = 14
Number of more yellow stickers than green stickers
= 4 u - 1 u
= 3 u
3 u = 60
1 u = 60 ÷ 3 = 20
Number of blue stickers
= 98 u
= 98 x 20
= 1960
Answer(s): 1960
