    If \[a=3,\,b=5,\,c=b-a,\] then which of the following expressions represent 10?

    A)  \[(a+c)\times b\]        

    B)    \[(a+b)-c\]

    C)  \[(b+c)+a\]   

    D)    \[(a-b)+c\]

    Correct Answer: C

    Solution :

         Given \[a=3,\,b=5,\,c=b-a=5-3=2\] Putting these values, we will evaluate all the expressions  \[(a+c)\times b=(3+2)\,\times 5=5\times 5=25\ne 10\]  \[(a+b)\,-c=(3+5)\,-2=8-2=6\ne 10\]  \[(b+c)\,+a=(5+2)\,+3=7+3=10\]  \[(a-b)\,+c=(3-5)\,+2=-2\,+2=0\ne 10\]
