Solution:

QUESTION: 6

Consider the following Linear Programming Problem (LPP):

Maximize z = 3x_{1} + 2x_{2}

Subject to x_{1} ≤ 4

x_{2} ≤ 6

3x_{1} + x_{2} ≤ 18

x_{2} ≥ 0, x_{2} ≥ 0

Solution:

A feasible solution to the linear programming problem should satisfy the problem constraints.

QUESTION: 15

Assertion (A): Double sampling is preferred over single sampling when the quality or incoming lots is expected to be either very good or very bad.

Reason (R): With double sampling, the amount of inspection required will be lesser than that in the case of single sampling.
