ITERATION 1
For node A
Numerator will contain pages that point to A i.e. C
Denominator will contain outgoing links from C
PR(C) = 1 [initially 1]
C(C)= 1 [outgoing links from C]
d= 0.85 [ default value if not given in the question]
PR(A)
= (1-d) + d [ PR(C) /C (C)]
= (1- 0.85) + 0.85
[1/1]
=
1
For node B
Numerator will contain pages that point to B i.e. A
Denominator will contain outgoing links from A= There are 2 outgoing
links from A
PR(A) = 1 [initially 1]
C(A)= 2 [outgoing links from A]
d= 0.85 [ default value if not given in the question]
PR(B)
= (1-d) + d [ PR(A) /C (A)]
= (1- 0.85) + 0.85
[1/2]
=
0.575
For node C
Numerator will contain pages that point to C i.e. A and B
Denominator will contain outgoing links from A and B
PR(A) = 1 [initially 1]
C(A)= 2 [outgoing links from A]
PR(B) = 1 [Taken from the above calculation]
C(B)= 1 [outgoing links from C]
d= 0.85 [ default value if not given in the question]
PR(C)
= (1-d) + d [ PR(A) /C (A) + PR(B)/ C(B)]
= (1- 0.85) + 0.85
[1/2 + 0.575/1]
=
1.06375
ITERATION 2
For node A
Numerator will contain pages that point to A i.e. C
Denominator will contain outgoing links from C
PR(C) = 1.06375 [from earlier iteration]
C(C)= 1 [outgoing links from C]
d= 0.85 [ default value if not given in the question]
PR(A)
= (1-d) + d [ PR(C) /C (C)]

For node B
Numerator will contain pages that point to B i.e. A

For node C
Numerator will contain pages that point to C i.e. A and B
Denominator will contain outgoing links from A and B
PR(C)
= (1-d) + d [ PR(A) /C (A) + PR(B)/ C(B)]
