3 brothers share some stickers.
Adam has 40 more than Bryan.
Bryan has 3 times as many as Charlie.
Adam and Bryan have 600 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 + 40
Number of stickers that Adam and Bryan have is 600 more than Charlie.
Number
of stickers that Adam and Bryan have = 1 u + 600 3 u + 40 + 3 u = 1 u + 600 6 u - 1 u = 600 - 40 5 u = 560
1 u = 560 ÷ 5 = 112 (a)
Number of stickers that Bryan has
= 3 x 112
= 336
(b)
Number of stickers that Adam has
= 3 u + 40
= 3 × 112 + 40
= 336 + 40
= 376
(c)
Number of stickers that Adam and Charlie have
= 3 u + 40 + 1 u
= 376 + 112
= 488
Answer(s): (a) 336; (b) 376; (c) 488
