value of attribute R. Therefore, it is true that:

(A) P ®Q

(B) P ®R

(C) P ® (Q,R).

(D) (Q,R)® P

Ans.: A.

Reason: Value of P matches only with value of Q

IMPORTANT SOLVED MODEL TEST PAPER FOR UGC NET DECEMBER 2014

1. The total number of spanning trees that can be drawn using five labeled vertices is:

(A). 125 (B).64

(C ). 36 (D). 16

Ans : A.

Explanation:

As per Cayleys formula for counting spanning trees

T(Kn)= n^ (n-2) where n is the number of vertices.

T(k5)=5 5-2=5 3= 5 * 5 * 5=125

2. Four jobs J1,J2,J3, and J4 are waiting to be run. Their expected run times are 9,6,3 and 5 respectively. In order to minimize average response time, the jobs should be run in the order:

(C ) J3 J4 J1 J2 (D) J3 J4 J2 J1

Ans : D

Easy one

J3=3

J4=5

J2=6

J1=9

3. If a code is ‘t’ error detecting, the minimum hamming distance should be equal to :

(A). t-1 (B). t

(C ). t+1 (D). 2t+1

Ans: C.

Very often asked question.

Tip:

For error detection, formula is t+1

For error correction, formula is 2t+1
