Given a flow graph with 10 nodes, 13 edges and one connected components, the number of regions and the number of predicate(decision) nodes in the flow graph will be

• 4,5

• 5,4

• 3,1

• 13,8

Cyclomatic complexity of a flow graph G with n vertices and e edges is

• V(G)=e+n-2

• V(G)=e-n+2

• V(G)=e+n+2

• V(G)=e-n-2

Which one of the following statements is incorrect ?

• The number of regions corresponds to the cyclomatic complexity.

• Cyclometric complexity for a flow graph G is V(G) = N – E + 2, where E is the number of edges and N is the number of nodes in the flow graph.

• Cyclometric complexity for a flow graph G is V(G) = E – N + 2, where E is the number of edges & N is the number of nodes in the flow graph.

• Cyclometric complexity for a flow graph G is V(G) = P + 1, where P is the number of predicate nodes contained in the flow graph G.

In final examination, student can get 0 to 3000 marks. Students has to get 50% in order to pass the examination. If he gets 2000 or below that he will be given C grade ,if he gets 2000-2500 then he will get B grade and above that he is eligible for A grade. Using boundary value analysis what will be the values for testing if we are testing for C grade?

• 1500,1501,1999,2000

• 1499,1500,1999,2000

• 1500,1501,2000,2001

• 1499,1500,2000,2001

A theme park charges entry fee based on age group. For children below 3 it charges nothing, for 3-10 it charges 500/-, for 10-18 it charges 800/-,then for 18-60 it charges 1000 and above 60 it charges 500 again. Using boundary value analysis, what will be the values to test if person pays 500 rs entry fee?

• 0,2,3

• 2,3,10,11,59,60

• 2,3,10,11,59,60,100,101

• 59,60,100,101
