    If \[a*b=2a-3b+ab,\] then \[3*5+5*3\]is equal to :

    A) 22                    

    B) 24

    C) 26                    

    D) 28

    Correct Answer: A

    Solution :

    \[a*b=2a-3b\text{ }ab\] \[\Rightarrow \,\,\,3*5=2\times 3-3\times 5+3\times 5=6\] \[5*3=2\times 5-3\times 3+3\times 5\] \[=10-9+15=16\] Therefore. \[3*5+5*3\] \[=\text{ }6+16=22\]
