Charlie, Adam and Bryan have some stickers in the ratio of 3 : 1 : 1.
Charlie and Adam have a total of 800 stickers.
- How many stickers does Charlie have?
- How many stickers do Charlie and Bryan have?
- How many less stickers does Adam have than Charlie?
(a)
Number of stickers that Charlie has = 3 u
Number of stickers that Adam has = 1 u
Number of stickers that Bryan has = 1 u
Number of stickers Charlie and Adam have
= 3 u + 1 u
= 4 u
4 u = 800
1 u = 800 ÷ 4 = 200
Number of stickers that Charlie has
= 3 u
= 3 x 200
= 600
(b)
Number of stickers that Charlie and Bryan have
= 3 u + 1 u
= 4 u
= 4 x 200
= 800
(c)
Number of less stickers that Adam has than Charlie
= 3 u - 1 u
= 2 u
= 2 x 200
= 400
Answer(s): (a) 600; (b) 800; (c) 400
