The table given below represents the cost, revenue and tax rate for XYZ Limited for a period of 8 years. Cost and revenue are given in Rs '000 crores.
Profit for any year = revenue — cost
Profit after tax for any year = profit of that year - tax of that year
tax on any year = tax rate of that year x profit of that year
Tax for year 1 (in Rs '000 crores) = $$\frac{20}{100}(800-600)=\frac{1}{5}\times200=40$$
=> Profit after tax for year 1 (in Rs '000 crores) = 200 - 40 = 160
Similarly, profit after tax (in Rs '000 crores) for year :
Year 2 : $$\frac{(100-22)}{100}(250)$$ = 195
Year 3 : $$\frac{(100-22)}{100}(300)$$ = 234
Year 4 : $$\frac{(100-25)}{100}(250)$$ = 187.5
Year 5 : $$\frac{(100-30)}{100}(300)$$ = 210
Year 6 : $$\frac{(100-30)}{100}(300)$$ = 210
Year 7 : $$\frac{(100-33)}{100}(360)$$ = 241.2
Year 8 : $$\frac{(100-15)}{100}(450)$$ = 382.5
=> Total sum = 160 + 195 + 234 + 187.5 + 210 + 210 + 241.2 + 382.5 = 1820.2
=> Ans - (C)
