3 boys share some stickers.
Adam has 30 more than Bryan.
Bryan has 3 times as many as Charlie.
Adam and Bryan have 200 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 + 30
Number of stickers that Adam and Bryan have is 200 more than Charlie.
Number
of stickers that Adam and Bryan have = 1 u + 200 3 u + 30 + 3 u = 1 u + 200 6 u - 1 u = 200 - 30 5 u = 170
1 u = 170 ÷ 5 = 34 (a)
Number of stickers that Bryan has
= 3 x 34
= 102
(b)
Number of stickers that Adam has
= 3 u + 30
= 3 × 34 + 30
= 102 + 30
= 132
(c)
Number of stickers that Adam and Charlie have
= 3 u + 30 + 1 u
= 132 + 34
= 166
Answer(s): (a) 102; (b) 132; (c) 166
