(a)
Before
Number of beads that Caden had = 1 u + 293
Number of beads that Ahmad had = 1 u
After
Number of beads that Caden had = 1 u + 293 + 43 = 4 u
Number of beads that Ahmad had = 1 u
1 u + 293 + 43 = 4u
1 u + 336 = 4 u
4 u - 1 u = 336
3 u = 336
1 u = 336 ÷ 3 = 112
(a)
Number of beads that Ahmad had
= 1 u
= 112
(b)
Number of beads that Caden and Ahmad had in the end
= 4 u + 1 u
= 5 u
= 5 x 112
= 560
Answer(s): (a) 112; (b) 560
