A) 8
B) 12
C) 21
D) 16
Correct Answer: D
Solution :
Let the number of vertices =n Given degree of each vertex =3 Then, total degree of simple graph = 3n We know that, Sum of all degree of simple graph \[=2\times \]number of edges in simple graph \[\Rightarrow \] \[3n=2\times (24)\] \[\Rightarrow \] \[n=2\times 8\] \[\Rightarrow \] \[n=16\]You need to login to perform this action.
