Year one:Ang earns: 2,000 x 12 = 24,000Bakar earns: (1000 x 12) + (100 + 200 + 300 + .......+1100) == 12000 + 5,600= 17,600Chan earns: 100 + 150 + 225 + 337∙5 + ........+ 6727∙587891 = 23,827∙09961Year two:Ang earns: 24,000 + 10% = 26,40026,400 / 24,000 = 1∙1 That is, 10% rise.Bakar earns: 17,600 - (50 + 100 + 150 + .......600) == 17,600 - 3950= 13,65013,650 / 17,600 = 0∙775568....(1 - 0∙775568....) * 100% = 22∙443... % Drop in income.
