Q2 A firm is engaged in producing two products. A and B. Each unit of product
A requires 2 kg of raw material and 4 labor hours for processing, where as
each unit of B requires 3 kg of raw materials and 3 labor hours for the same
type. Every week, the firm has an availability of 60 kg of raw material and
96 labor hours. One unit of product A sold yields Rs.40 and one unit of
product B sold gives Rs.35 as profit.
Formulate this as an Linear Programming Problem to determine as to how
many units of each of the products should be produced per week so that the
firm can earn maximum profit

Q5 6.A farmer is going to plant apples and bananas this year. It costs $ 40 per
acre to plant apples and $ 60 per acre to plant bananas and the farmer has a
maximum of $ 7400available for planting. To plant apples trees requires 20
labor hours per acre; to plant banana trees requires 25 labor hours. Suppose
the farmer has a total of 3300 labor hours available. If he expects to make a
profit of $ 150 per acre on apples and $ 200per acre on bananas, how many
acres each of apples and bananas should he cultivate? Formulate the problem
as LPP & solve Graphically

Q2 The coach of a swim team needs to assign swimmers to a 200-yard medley
relay team (four swimmers, each swims 50 yards of one of the four strokes).
Since most of the best swimmers are very fast in more than one stroke, it is
not clear which swimmer should be assigned to each of the four strokes. The
five fastest swimmers and their best times (in seconds) they have achieved in
each of the strokes (for 50 yards) are

B 4 2 7
The labour time for each unit of model I is twice that of model II & Thrice
that of model III. The entire labour force of factory can produce equivalent
of 2500 units of model I.A market survey indicates that the minimum
demand of three models is 500,500 & 375 units respectively. However the
rations of numbers of units produced must be equal to 3:2:5. Assume that
the profit per unit of models I,II,&III are Rs.60,Rs40,& Rs100 respectively.
Formulate the problem as LPP to determine number of units of each model
to maximize profit.

A firm is engaged in producing two products. A and B. Each unit of product
A requires 2 kg of raw material and 4 labour hours for processing, where as
each unit of B requires 3 kg of raw materials and 3 labour hours for the
same type. Every week, the firm has an availability of 60 kg of raw material
and 96 labour hours. One unit of product A sold yields Rs.40 and one unit
of product B sold gives Rs.35 as profit.
Formulate this as an Linear Programming Problem to determine as to how
many units of
each of the products should be produced per week so that the firm can earn
maximum profit
