Explain solution RD Sharma class 12 Chapter 29 Linear Programming exercise 29.4 question 52
Answer: The maximum total revenue is Rs.1260 when 3 units of A and 8 units of B are produced. Yes, because the efficiency of a worker does not depend on whether the worker is a male or female.
Hint:
Use property of LPP
Given:
That men and women workers are equally efficient and So, he pays them at the same rate.
Solution:
Let x unit of A and y units of B produced by the manufacturer.
The price of one unit of A is Rs.100 and the price of one unit of B is Rs.120. Therefore, the total price of x unit of A and y units of B. The total revenue is Rs. (100x+120y) one unit of A requires 2 workers are one unit of B requires 3 workers. Therefore x unit of A and y units of B requires (2x + 3y) workers. But, the manufacturer has 30 workers.
Similarly, one unit of A requires 3 units of capital. Therefore, x unit of A and y unit of B requires (3x+y) units of capital. Therefore, x unit of A and y unit of B requires (3x + y) units of capital. But the manufacturer has 17 units of capital.
The feasible region determined by the given constraints can be diagrammatically represented as.
The coordinates of the corner points of the feasible region are O(0,0), A(0,10), B(17/3,0) and C(3,8)
The value of the objective function at these points is given in the following table.

The maximum value of Z is 1260 at x=3 and y=8.
Hence the maximum total revenue is Rs.1260 when 3 units of A and 8 units of B are produced.
Yes, because the efficiency of a worker does not depend on whether the worker is a male or female.
