3 cousins share some stickers.
Bryan has 40 more than Adam.
Adam has 3 times as many as Charlie.
Bryan and Adam have 200 more than Charlie.
- How many stickers does Adam have?
- How many stickers does Bryan have?
- How many stickers do Bryan 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 Adam has = 3 u
Number of stickers that Bryan has = 3 u + 40
Number of stickers that Bryan and Adam have is 200 more than Charlie.
Number
of stickers that Bryan and Adam have = 1 u + 200 3 u + 40 + 3 u = 1 u + 200 6 u - 1 u = 200 - 40 5 u = 160
1 u = 160 ÷ 5 = 32 (a)
Number of stickers that Adam has
= 3 x 32
= 96
(b)
Number of stickers that Bryan has
= 3 u + 40
= 3 × 32 + 40
= 96 + 40
= 136
(c)
Number of stickers that Bryan and Charlie have
= 3 u + 40 + 1 u
= 136 + 32
= 168
Answer(s): (a) 96; (b) 136; (c) 168
