Use Simplex method to
Maximize Ζ = 4x + 10x2
Subject 2X+X2 ≤ 50
2X + 5X2 ≤ 100
2X + 3X2 ≤ 100
X, X2 ≥ 0
The problem is converted to canonical form by adding slack, surplus and artificial variables as appropriate
1. As the constraint-1 is of type '≤' we should add slack variable S1
2. As the constraint-2 is of type '≤' we should add slack variable S2
3. As the constraint-3 is of type '≤' we should add slack variable S3
After introducing slack variables
Negative minimum is -10 and its column index is 2. So, the entering variable is .
Minimum ratio is 20 and its row index is 2. So, the leaving basis variable is .
∴ The pivot element is 5.
Entering = , Departing = , Key Element =5
Since all
Hence, optimal solution is arrived with value of variables as :
Max Z = 200
