Solution

SOl)

Entering =X2, Departing =S2, Key Element = 3

R2 (new) =R2 (old) ÷3=R2 (old) 1/3

R1 (new) =R1 (old) 2R2 (new)

Entering =X1, Departing =S1, Key Element = 5/3

R1 (new) =R1 (old) ÷53=R1 (old) 3/5

R2(new) =R2 (old) +1/3R1(new)

Since all CjZj0,

Optimum Solution is arrived with value of variables as :
X1=0.1

X2=0.2

Maximise Z=1.1
