Step 1: If the objective function \( Z = ax + by \) in a Linear Programming Problem (LPP) yields the same value at two corner points of the feasible region, the maximum value of \( Z \) will be attained at all points along the line segment connecting these two corner points.
Step 2: As the line segment comprises an infinite number of points, the quantity of points where \( Z \) achieves its maximum value is infinite.
A man bought an item for ₹ 12,000. At the end of the year, he decided to sell it for ₹ 15,000. If the inflation rate was 6%, find the nominal and real rate of return.
