(a)
Before
Number of buttons that Henry had = 1 u + 337
Number of buttons that Ahmad had = 1 u
After
Number of buttons that Henry had = 1 u + 337 + 56 = 4 u
Number of buttons that Ahmad had = 1 u
1 u + 337 + 56 = 4u
1 u + 393 = 4 u
4 u - 1 u = 393
3 u = 393
1 u = 393 ÷ 3 = 131
(a)
Number of buttons that Ahmad had
= 1 u
= 131
(b)
Number of buttons that Henry and Ahmad had in the end
= 4 u + 1 u
= 5 u
= 5 x 131
= 655
Answer(s): (a) 131; (b) 655
