1.

The point of optimal solution occurs at the intersection of two lines:

E1=p1+2p2E_1=-p_1+2p_2

E2=p1E_2=p_1

p1+2p2=p1-p_1+2p_2=p_1


p2=1p1p_2=1-p_1

p1=p2=0.5p_1=p_2=0.5

Substituting the values of p1 and p2 in equation E2 :

V=0.5+20.5=0.5V=-0.5+2\cdot0.5=0.5


2.

The point of optimal solution occurs at the intersection of two lines:

L1=q1+q2L_1=-q_1+q_2

L2=2q1L_2=2q_1

q1+q2=2q1-q_1+q_2=2q_1


q2=1q1q_2=1-q_1

3q1=1q13q_1=1-q_1

q1=1/4,q2=3/4q_1=1/4, q_2=3/4

Substituting the values of q1 and q2 in equation L2 :

V=0.25+0.75=0.5V=-0.25+0.75=0.5
