3 boys share some stickers.
Adam has 60 more than Bryan.
Bryan has 3 times as many as Charlie.
Adam and Bryan have 200 more than Charlie.
- How many stickers does Bryan have?
- How many stickers does Adam have?
- How many stickers do Adam and Charlie have?
Choose the person with least stickers to be 1 u.
Number of stickers that Charlie has = 1 u
Number of stickers that Bryan has = 3 u
Number of stickers that Adam has = 3 u + 60
Number of stickers that Adam and Bryan have is 200 more than Charlie.
Number
of stickers that Adam and Bryan have = 1 u + 200 3 u + 60 + 3 u = 1 u + 200 6 u - 1 u = 200 - 60 5 u = 140
1 u = 140 ÷ 5 = 28 (a)
Number of stickers that Bryan has
= 3 x 28
= 84
(b)
Number of stickers that Adam has
= 3 u + 60
= 3 × 28 + 60
= 84 + 60
= 144
(c)
Number of stickers that Adam and Charlie have
= 3 u + 60 + 1 u
= 144 + 28
= 172
Answer(s): (a) 84; (b) 144; (c) 172
