Option IV) 8,7,7,6,4,2,1,1 , here degree of a vertex is 8 and total number of vertices are 8 , so it’s impossible, hence it’s not graphical. Note that path graph, Pn, has n-1 edges, and can be obtained from cycle graph, C n, by removing any edge. Any k-regular graph where kis an even number. b) C and D Following are planar embedding of the given two graph, Let G = (V,E) be a graph. A plane graph having ‘n’ vertices, cannot have more than ‘2*n-4’ number of edges. There is always one unbounded face, so the number of bounded faces =  6, Which of the following graphs is isomorphic to, Let G be a complete undirected graph on 6 vertices. III. A generic algorithm or method to solve this question is 1: procedure isV alidDegreeSequence(L) 2: for n in list L do 3: if L doesn’t have n elements next to the current one then return false 4: decrement next n elements of the list by 1 5: arrange it back as a degree sequence, i.e. Since the graph is connected, the degree of any vertex cannot be 0. The value of 6C4 is 15. The resultant graph is two edge connected, and of minimum degree 2 but there exist a cut vertex, the merged vertex. = 800 + [(3 + 5*10 + 3) + 5*10] + [(3 + 5*10 + 3) + 5*10] d) Must have no multiple edges Enumerating the f alse returns, 1) if L doesn’t have enough elements after the current one or 2) if any element of the list becomes negative, then it means that there aren’t enough nodes to accommodate edges in a simple graph fashion, which will lead to violation of either of the two conditions of the simple graph (no self-loops and no multiple-edges between two nodes), if not others. This contains 20 Multiple Choice Questions for Computer Science Engineering (CSE) Graphs Theory MCQ - 1 (mcq) to study with solutions a complete question bank. View Answer, 14. c) (n*n-n-2*m)/2 Hence tuple <3, 3, 3, 1, 0, 0> is not graphic. d) (n*n-n+2*m)/2 B) FALSE: An Eulerian Graph may or may not be planar.An undirected graph is eulerian if all vertices have even degree. Let us analyze all options. a) A graph may contain no edges and many vertices Try this amazing The Cardiac Cycle Quiz Questions!

If a simple graph G, contains n vertices and m edges, the number of edges in the Graph G'(Complement of G) is ___________ Same is count for (12, 12), (1, 12) and (12, 1) b) G is not a connected graph A wheel graph is obtained from a cycle graph C n-1 by adding a new vertex. View Answer, 7. So adding one edge to the graph will make it a non planar graph. Bipartite Graphs A bipartite graph is a graph whose vertex-set can be split into two sets in such a way that each edge of the graph joins a vertex in first set to a vertex in second set. a cut edge e ∈ G if and only if the edge ‘e’ is not a part of any cycle in G. So total number of distinct cycles is (15*3) = 45. Then G has. (Q) The line graph of a clique is a clique. b) False A Graph is said to be planar if it can be drawn in a plane without any edges crossing each other. Option III) 7,6,6,4,4,3,2,2 → 5,5,3,3,2,1,1 → 4,2,2,1,1,0 → 1,1,0,0,0 → 0,0,0,0 so its graphical. Which of the following properties does a simple graph not hold? f = 7 Data Structure MCQ - Graph. View Answer, 9. Page 1. A) FALSE: A disconnected graph can be planar as it can be drawn on a plane without crossing edges. A) True, False, True B) True, True, False C) True, True, True D) False, True, True A graph drawn in a plane in such a way that any pair of edges meet only at their end vertices : A graph drawn in a plane in such a way that if the vertex set of graph can be partitioned into two non - empty disjoint subset X and Y in such a way that each edge of G has one end in X and one end in Y . b) 21 Let V(G1)={1,2,3,4} and V(G2)={5,6,7,8}. If we add a vertex, then the new vertex (if it is not the first node) increases degree by 2, it doesn't matter where we add it. (S) The line graph of a tree is a tree. (Such a closed loop must be a cycle.) Let's see this with the help of a logical structure of the graph : Let's say vertices labelled as should have their degree as <3, 3, 3, 1, 0, 0> respectively. **NOTE**: In original GATE question paper 45 was not an option. For example, consider 4 vertices as a, b, c and d. The three distinct cycles are cycles should be like this (a, b, c, d,a) (a, b, d, c,a) (a, c, b, d,a) (a, c, d, b,a) (a, d, b, c,a) (a, d, c, b,a) and (a, b, c, d,a) and (a, d, c, b,a) (a, b, d, c,a) and (a, c, d, b,a) (a, c, b, d,a) and (a, d, b, c,a) are same cycles. An ordered n-tuple (d1, d2, … , dn) with d1 >= d2 >= ⋯ >= dn is called graphic if there exists a simple undirected graph with n vertices having degrees d1, d2, … , dn respectively. The solved questions answers in this Graphs Theory MCQ - 1 quiz give you a good mix of easy questions and tough questions. For all pairs (i, j) there can total 8 vertices connected to them if i and j are not in {1, 12} There are total 100 vertices without a 1 or 12. c) Simple Graph View Answer, 3.
