    The sum of A plus B equals 116. A is 3 less than C, but 4 more than B. What number does C equal?

    A)  72       

    B)         48  

    C)  53       

    D)  63

    Correct Answer: D

    Solution :

    \[\because \]\[A+B=116\]                                            ?(i) and       \[A=C-3\]                                  ?(ii) \[\because \]       \[A=B+4\] \[B=A-4=(C-3)-4\]                      ?(iii) \[=C-7\] On putting the value of A and B in Eq. (i), then \[(C-3)+(C-7)=116\] \[\Rightarrow \]   \[2C=116+10=126\] \[\therefore \]                  \[C=\,\,63\]
