Q41,paper 3,D 12.Consider a system having m resources of the same type. These resources are shared by 3 processes A, B and C which have peak demands of 3, 4 and 6 respectively. For what value of m deadlock will not occur ?

(A) 7

(B) 9

(C) 10

(D) 13.

Answer(d).

Explanation.

Total of max needs < (no. of resource instances + no. of processes)

(3+4+6)< m+3.

m>10. hence m should be eleven or above. Only 13 qualify the criteria.
