Charlie, Adam and Bryan have some stickers in the ratio of 3 : 1 : 4.
Charlie and Adam have a total of 500 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 = 3 u
Number of stickers that Adam has = 1 u
Number of stickers that Bryan has = 4 u
Number of stickers Charlie and Adam have
= 3 u + 1 u
= 4 u
4 u = 500
1 u = 500 ÷ 4 = 125
Number of stickers that Charlie has
= 3 u
= 3 x 125
= 375
(b)
Number of stickers that Charlie and Bryan have
= 3 u + 4 u
= 7 u
= 7 x 125
= 875
(c)
Number of more stickers that Charlie has than Adam
= 3 u - 1 u
= 2 u
= 2 x 125
= 250
Answer(s): (a) 375; (b) 875; (c) 250
