Please tell the formula for (ii) & (iii)

Dear Student
 
(ii)Total Consumption Expenditure = Sale to Private Consumers + Sale to Government
                                                       = 800 + 500
Total Consumption Expenditure     = Rs 1300

 (iii) Saving and investment  = Unsold Stock + exports
                                            = 500 + 600
Saving and investment     = Rs 1100
