3 brothers share some stickers.
Bryan has 30 more than Adam.
Adam has 3 times as many as Charlie.
Bryan and Adam have 600 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 + 30
Number of stickers that Bryan and Adam have is 600 more than Charlie.
Number
of stickers that Bryan and Adam have = 1 u + 600 3 u + 30 + 3 u = 1 u + 600 6 u - 1 u = 600 - 30 5 u = 570
1 u = 570 ÷ 5 = 114 (a)
Number of stickers that Adam has
= 3 x 114
= 342
(b)
Number of stickers that Bryan has
= 3 u + 30
= 3 × 114 + 30
= 342 + 30
= 372
(c)
Number of stickers that Bryan and Charlie have
= 3 u + 30 + 1 u
= 372 + 114
= 486
Answer(s): (a) 342; (b) 372; (c) 486
