Solution

The correct option is B 0
The unit worth of resources $R_{2},$ i.e. dual price of resources $R_{2},$ in Rs. per kg is zero because the constraint (2) is redundant. Therefore resources $R_{2},$ has no effect on the feasible solution.

Q. A factory uses three different resources for the manufacture of two different products, 20 units of the resources A, 12 units of B and 16 units of C being available. 1 unit of the first product requires 2, 2 and 4 units of the respective resources and 1 unit of the second product requires 4, 2 and 0 units of respective resources. It is known that the first product gives a profit of 2 monetary units per unit and the second 3. Formulate the linear programming problem. How many units of each product should be manufactured for maximizing the profit? Solve it graphically.

When resistors $R_{1}$ and $R_{2}$ are connected in series across a battery of potential difference $V,$ the power dissipated by the resistors are $P_{1}$ and $P_{2}$ respectively. When they are connected in parallel across a battery of potential difference $E,$ the power dissipated is $P_{3}$ and $P_{4}$ respectively. Which one of the following is true?
