Q1 1. Explain Graphical method of solving LPP

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

raw materials A & B of which 4000 & 6000 units

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
