Adam has stickers in 4 colours.
27 of the stickers are red.
The rest of the stickers are yellow, blue and green in the ratio of 1 : 4 : 6.
If there are 150 more blue stickers than yellow stickers,
how many red stickers are there?
Red |
Yellow |
Blue |
Green |
2 x 11 |
5 x 11 |
|
1 x 5 |
4 x 5 |
6 x 5 |
22 u |
5 u |
20 u |
30 u |
The number of red, yellow and blue stickers is the combined repeated identity.
Make the number of red, yellow and blue stickers the same using the LCM of 5 and 11.
LCM of 5 and 11 = 55
Number of more blue stickers than yellow stickers
= 20 u - 5 u
= 15 u
15 u = 150
1 u = 150 ÷ 15 = 10
Number of red stickers
= 22 u
= 22 x 10
= 220
Answer(s): 220
