3 cousins share some stickers.
Adam has 50 more than Charlie.
Charlie has 3 times as many as Bryan.
Adam and Charlie have 600 more than Bryan.
- How many stickers does Charlie have?
- How many stickers does Adam have?
- How many stickers do Adam and Bryan have?
Choose the person with least stickers to be 1 u.
Number of stickers that Bryan has = 1 u
Number of stickers that Charlie has = 3 u
Number of stickers that Adam has = 3 u + 50
Number of stickers that Adam and Charlie have is 600 more than Bryan.
Number
of stickers that Adam and Charlie have = 1 u + 600 3 u + 50 + 3 u = 1 u + 600 6 u - 1 u = 600 - 50 5 u = 550
1 u = 550 ÷ 5 = 110 (a)
Number of stickers that Charlie has
= 3 x 110
= 330
(b)
Number of stickers that Adam has
= 3 u + 50
= 3 × 110 + 50
= 330 + 50
= 380
(c)
Number of stickers that Adam and Bryan have
= 3 u + 50 + 1 u
= 380 + 110
= 490
Answer(s): (a) 330; (b) 380; (c) 490
