A firm manufactures two products, each of which must be processed through two departments, 1 and 2. The hourly requirements per unit for each product in each department, the weekly capacities in each department, selling price per unit, labour cost per unit, and raw material cost per unit are summarized as follows:

 Product A Product B Weekly capacity Department 1 3 2 130 Department 2 4 6 260 Selling price per unit ₹ 25 ₹ 30 Labour cost per unit ₹ 16 ₹ 20 Raw material cost per unit ₹ 4 ₹ 4

The problem is to determine the number of units to produce each product so as to maximize total contribution to profit. Formulate this as a LPP.

##### Solution :-

Let x be the number of units of product A.

Let y be the number of units of product B.

Profit per unit

=Selling price per unitLabour cost per unit−Raw material cost per unit

Profit on one unit of product A=25−16−4=Rs 5

Profit on one unit of product B=30−20−4=Rs 6

Total profit, Z=5x+6y

According to the question,

3x+2y≤130

4x+6y≤260
