Adam has stickers in 4 colours.
710 of the stickers are blue.
The rest of the stickers are yellow, green and red in the ratio of 3 : 4 : 7.
If there are 150 more green stickers than yellow stickers,
how many blue stickers are there?
Blue |
Yellow |
Green |
Red |
7 x 14 |
3 x 14 |
|
3 x 3 |
4 x 3 |
7 x 3 |
98 u |
9 u |
12 u |
21 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 3 and 14.
LCM of 3 and 14 = 42
Number of more green stickers than yellow stickers
= 12 u - 9 u
= 3 u
3 u = 150
1 u = 150 ÷ 3 = 50
Number of blue stickers
= 98 u
= 98 x 50
= 4900
Answer(s): 4900
