Question 1

Four matrices M1, M2, M3 and M4 of dimensions p x q, q x r, r x s and s x t respectively can be multiplied in several ways with different number of total scalar multiplications. For example, when multiplied as ((M1 x M2) x (M3 x M4)), the total number of multiplications is pqr + rst + prt. When multiplied as (((M1 x M2) x (M3) x M4), the total number of scalar multiplications is pqr + prs + pst.
If p = 10, q = 100, r = 20, s = 5 and t = 80, then the number of scalar multiplications needed is

Question 2

The Cyclomatic complexity of each of the modules A and B shown below is 10. What is the Cyclomatic complexity of the sequential integration shown on the right hand side?

Question 3

What is the average Access Time for a Drum rotating at 4000 revolutions per minute?

Question 4

Consider the tree given below:

Using the property of eccentricity of a vertex, find every vertex that is the centre of the given tree.

Question 5

Two graphs A and B are shown below: Which one of the following statement is true?

Question 6

In order to implement a n variable switching function, a MUX must have:

Question 7

“If my computations are correct and I pay the electric bill, then I will run out of money. If I don’t pay the electric bill, the power will be turned off. Therefore, if I don’t run out of money and the power is still on, then my computations are incorrect.”
Convert this argument into logical notations using the variables c, b, r, p for propositions of computations, electric bills, out of money and the power respectively. (Where ¬means NOT)

Question 8

Consider the compound propositions given below:
(A) PV~(P^Q)

(B) (P^~Q)v~(P^Q)

(C) P^(QvR)

Which of the above propositions are tautologies?

Question 9

The initial basic feasible solution to the following transportation problem using Vogel’s approximation method is
