    Which of the following is a solution of\[\text{2p}+\text{3q}=\text{5}\]?

    A)  \[\text{p}=-\text{1},\text{q}=\text{1}\]              

    B)         \[\text{p }=\text{ 1},\text{ q }=\text{ }-\text{1}\]

    C)  \[\text{p}=\text{1},\text{q}=\text{1}\]               

    D)         \[~\text{p}=-\text{1},\text{q}=-\text{1}\]

    Correct Answer: C

    Solution :

     Substitute the given values of 'p' and 'q' in 2p + 3q = 5 and check whether the equation is satisfied. Substituting p = 1 and q = 1 in 2p + 3q = 5, makes it true.
