3 children share some stickers.
Adam has 20 more than Charlie.
Charlie has 3 times as many as Bryan.
Adam and Charlie have 600 more than Bryan.
- How many stickers does Charlie have?
- How many stickers does Adam have?
- How many stickers do Adam and Bryan have?
Choose the person with least stickers to be 1 u.
Number of stickers that Bryan has = 1 u
Number of stickers that Charlie has = 3 u
Number of stickers that Adam has = 3 u + 20
Number of stickers that Adam and Charlie have is 600 more than Bryan.
Number
of stickers that Adam and Charlie have = 1 u + 600 3 u + 20 + 3 u = 1 u + 600 6 u - 1 u = 600 - 20 5 u = 580
1 u = 580 ÷ 5 = 116 (a)
Number of stickers that Charlie has
= 3 x 116
= 348
(b)
Number of stickers that Adam has
= 3 u + 20
= 3 × 116 + 20
= 348 + 20
= 368
(c)
Number of stickers that Adam and Bryan have
= 3 u + 20 + 1 u
= 368 + 116
= 484
Answer(s): (a) 348; (b) 368; (c) 484
