Charlie has thrice as many beads as Jeremy. Jeremy has 5 more beads than Seth. They have a total of 135 beads.
- How many beads does Charlie have?
- How many beads does Seth have?
(a)
Number of beads that Jeremy has = 1 u
Number of beads that Seth has = 1 u - 5
Number of beads that Charlie has = 3 u
Total number of beads
= 1 u + 1 u - 5 + 3 u
= 5 u - 5
5 u - 5 = 135
5 u = 135 + 5
5 u = 140
1 u = 140 ÷ 5 = 28
Number of beads that Charlie has
= 3 u
= 3 x 28
= 84
(b)
Number of beads that Seth has
= 1 u - 5
= 28 - 5
= 23
Answer(s): (a) 84; (b) 23
