Hilda has 6 beads fewer than Linda but 12 beads more than Ahmad. The three children have 261 beads altogether.
- How many beads does Ahmad have?
- How many beads does Linda have?
(a)
Number of beads Linda has = 1 u
Number of beads Hilda has = 1 u - 6
Number of beads Ahmad has = 1 u - 6 - 12 = 1 u - 18
Total number of beads
= 1 u + 1 u - 6 + 1 u - 18
= 3 u - 24
3 u - 24 = 261
3 u = 261 + 24
3 u = 285
1 u = 285 ÷ 3 = 95
Number of beads that Ahmad has
= 1 u - 18
= 95 - 18
= 77
(b)
Number of beads that Linda has
= 1 u
= 95
Answer(s): (a) 77; (b) 95
