    Which of the following conclusions is correct according to the given expression and symbols? \[a\,\Delta \,b\,\phi \,c\]             \[a+b\,\theta \,c\]        \[a\,\phi \,b\,\theta \,c\] \[b\,\theta \,c\,\square \,a\]        \[c+b\times a\]             \[a\times b\,\theta \,c\]  Expression (qEq) and (qEr)

    A) pEr             

    B) pFr

    C) rBp                             

    D) rBq

    Correct Answer: A

    Solution :

        pEq and qFr \[=8+10\times 3\div 5-6\] p \[=8+10\times 3\times \frac{1}{5}-6=8+6-6=8\]q and q \[(3\div 4)+2=2\] r \[a\ne b\]p \[p\Delta q\]r \[p\times q\times r\]pEr So, the answer is (a)
