Assertion (A): The shaded portion of the graph represents the feasible region for the given Linear Programming Problem (LPP).
Reason (R): The region representing \( Z = 50x + 70y \) such that \( Z < 380 \) does not have any point common with the feasible region.
Both Assertion (A) and Reason (R) are true and the Reason (R) is the correct explanation of the Assertion (A)
Both Assertion (A) and Reason (R) are true and the Reason (R) is the correct explanation of the Assertion (A)
- The feasible region is the area that satisfies all the given constraints for the Linear Programming Problem (LPP).
This region is bounded by the lines representing the constraints. The graph shows this feasible region as the shaded portion. Therefore, Assertion (A) is correct.
- The objective function is \( Z = 50x + 70y \). The given condition \( Z = 50x + 70y \) has a minimum value of 380 at the point \( B(2, 4) \).
- If \( Z < 380 \), this means the values of \( x \) and \( y \) are outside the feasible region, as the region representing \( Z = 50x + 70y \) less than 380 does not intersect the feasible region. Thus, Reason (R) correctly explains why the region \( Z < 380 \) does not intersect the feasible region.
Hence, both Assertion (A) and Reason (R) are correct, and Reason (R) is the correct explanation for Assertion (A).
Determine whether each of the following relations are reflexive, symmetric, and transitive.
Show that the relation R in the set R of real numbers, defined as
R = {(a, b): a ≤ b2 } is neither reflexive nor symmetric nor transitive.
Check whether the relation R defined in the set {1, 2, 3, 4, 5, 6} as
R = {(a, b): b = a + 1} is reflexive, symmetric or transitive.
Reshma wishes to mix two types of food P and Q in such a way that the vitamin contents of the mixture contain at least 8 units of vitamin A and 11 units of vitamin B.Food P costs Rs.60/kg and food Q costs Rs.80/kg. Food P contains 3 units/kg of vitamin A and 5 units/kg of vitamin B while food Q contains 4units/kg of vitamin A and 2 units/kg of vitamin B. Determine the minimum cost of the mixture.
One kind of cake requires 200g of flour and 25g of fat, and another kind of cake requires 100g of flour and 50g of fat. Find the maximum number of cakes that can be made from 5kg of flour and 1kg of fat assuming that there is no shortage of the other ingredients used in making the cakes.
A manufacturer produces nuts and bolts. It takes 1 hour of work on machine A and 3 hours on machine B to produce a package of nuts. It takes 3 hours on machine A and 1 hour on machine B to produce a package of bolts. He earns a profit of Rs17.50 per package on nuts and Rs7.00 per package on bolts. How many packages of each should be produced each day so as to maximize his profit, if he operates his machines for at the most 12 hours a day?
