Charlie, Adam and Bryan have some stickers in the ratio of 4 : 1 : 1.
Charlie and Adam have a total of 400 stickers.
- How many stickers does Charlie have?
- How many stickers do Charlie and Bryan have?
- How many more stickers does Charlie have than Adam?
(a)
Number of stickers that Charlie has = 4 u
Number of stickers that Adam has = 1 u
Number of stickers that Bryan has = 1 u
Number of stickers Charlie and Adam have
= 4 u + 1 u
= 5 u
5 u = 400
1 u = 400 ÷ 5 = 80
Number of stickers that Charlie has
= 4 u
= 4 x 80
= 320
(b)
Number of stickers that Charlie and Bryan have
= 4 u + 1 u
= 5 u
= 5 x 80
= 400
(c)
Number of more stickers that Charlie has than Adam
= 4 u - 1 u
= 3 u
= 3 x 80
= 240
Answer(s): (a) 320; (b) 400; (c) 240
