Pamela has 14 beads fewer than Olivia but 39 beads more than Japheth. The three children have 164 beads altogether.
- How many beads does Japheth have?
- How many beads does Olivia have?
(a)
Number of beads Olivia has = 1 u
Number of beads Pamela has = 1 u - 14
Number of beads Japheth has = 1 u - 14 - 39 = 1 u - 53
Total number of beads
= 1 u + 1 u - 14 + 1 u - 53
= 3 u - 67
3 u - 67 = 164
3 u = 164 + 67
3 u = 231
1 u = 231 ÷ 3 = 77
Number of beads that Japheth has
= 1 u - 53
= 77 - 53
= 24
(b)
Number of beads that Olivia has
= 1 u
= 77
Answer(s): (a) 24; (b) 77
