(ii) How much Material used by the optimal solution ? (iii) How much time used in Department 1? (iv) If the Increase in the objective coefficient of Product 1 is 5 units then what happens for the Optimal solution? How about objective function value? (v) If the objective coefficient of Product 4 is decreased by 5 units then what happened for optimal solution? (vi) If there are Simultaneous changes in objective coefficients of Product 2 and Product 3 such that the coefficients of product 2 increases by 2 units and coefficients of product 3 decreases by 7 units then what happened for optimal solution? (vii) If RHS value of the constraint Time in Department 2 decreases by 20 units then what happens for optimal solution? (viii) If we add a new constraint: P1 + P2200 to LP, what happens for optimal solution
