- Polynomial Functions
- Cofactors
- Extreme values
- Idempotent Matrix
- Non Singular Matrix
- Transpose of a Matrix

Subjective Part
Q.2:Given the demand and supply functions of a market.
Qd = 8 – 2P and Qs = 2+ 2P
Q.3: Determine the total demand for industries 1, 2, and 3, given the matrix of technical coefficient A and the final demand vector B below:
Q.4: Solve the following Linear Programming problem through graphical approach C = 12 X 1 + 42 X 2
Such that, X1 + 2 X 2 > 3
X1 + 4 X 2 > 4
3X1 + X 2 > 3
and X1 , X 2 > 0
Q.5: Use Camer’s rule to solve the following national income model:
Y = C + I + G
C = α + β (Y – T) (α > 0, 0 < β < 1)
T = γ + δY (γ >0, 0 < δ< 1)
Where Y, C and T are endogenous variables and I and G are exogenously determined.
Q.6: A firm is perfectly competitive producer and sells two goods G1 and G2 at $ 1000 and $800, respectively each. The total of producing these goods is given by
Where Q1 and Q2 denote the output levels of G1 and G2 respectively. Find the maximum profit and the values of Q1 and Q2 at which this is achieved.
Q.7: Optimize the objective function subject to the following constraints
Z = 8 x 2 + 6y2 – 2xy – 40 x – 42y + 180
Subject to:
X + Y = 5
- Use Lagrangian Multiplier Method for finding the value of X, Y & λ
- Use bordered Hessian determinant for 2nd order condition.
