3 brothers share some stickers.
Bryan has 40 more than Charlie.
Charlie has 3 times as many as Adam.
Bryan and Charlie have 300 more than Adam.
- How many stickers does Charlie have?
- How many stickers does Bryan have?
- How many stickers do Bryan and Adam have?
Choose the person with least stickers to be 1 u.
Number of stickers that Adam has = 1 u
Number of stickers that Charlie has = 3 u
Number of stickers that Bryan has = 3 u + 40
Number of stickers that Bryan and Charlie have is 300 more than Adam.
Number
of stickers that Bryan and Charlie have = 1 u + 300 3 u + 40 + 3 u = 1 u + 300 6 u - 1 u = 300 - 40 5 u = 260
1 u = 260 ÷ 5 = 52 (a)
Number of stickers that Charlie has
= 3 x 52
= 156
(b)
Number of stickers that Bryan has
= 3 u + 40
= 3 × 52 + 40
= 156 + 40
= 196
(c)
Number of stickers that Bryan and Adam have
= 3 u + 40 + 1 u
= 196 + 52
= 248
Answer(s): (a) 156; (b) 196; (c) 248
