Class XII

A company manufactures two types of novelty souvenirs made of plywood. Souvenirs of type A require 5 minutes each for cutting and 10 minutes each for assembling. Souvenirs of type B require 8 minutes each for cutting and 8 minutes each for assembling. There are 3 hours 20 minutes available for cutting and 4hours for assembling. The profit is Rs 5 each for type A and Rs 6 each for type B souvenirs. How many souvenirs of each type should the company manufacture in order to maximize the profit?
  1. 8 Souvenir of types A and 20 of Souvenir of type B; Maximum profit = Rs 160
  2. 8 Souvenir of types A and 27 of Souvenir of type B; Maximum profit = Rs 170
  3. 9 Souvenir of types A and 21 of Souvenir of type B; Maximum profit = Rs 163
  4. 7 Souvenir of types A and 210 of Souvenir of type B; Maximum profit = Rs 161
Which of the following types of problems cannot be solved by linear programming methods
  1. Diet problems
  2. Traffic signal control
  3. Transportation problems
  4. Manufacturing problems
In Corner point method for solving a linear programming problem the second step after finding the feasible region of the linear programming problem and determining its corner points is
  1. Evaluate the objective function Z = ax + by at the center point
  2. Evaluate the objective function Z = ax + by at the mid points
  3. None of these
  4. Evaluate the objective function Z = ax + by at each corner point.
Corner points of the feasible region for an LPP are (0, 2), (3, 0), (6, 0), (6, 8) and (0, 5).Let F = 4x + 6y be the objective function. Maximum of F – Minimum of F =
  1. 60
  2. 42
  3. 18
  4. 48
Let R be the feasible region for a linear programming problem,and let Z = ax + by be the objective function. If R is bounded, then the objective function Z has both a maximum and a minimum value on R and
  1. each of these occurs at some points except corner points of R.
  2. each of these occurs at themidpoints of the edges of R
  3. each of these occurs at the centre of R.
  4. each of these occurs at a corner point (vertex) of R.
