    If 721 and n are integers and \[\sqrt{mn}=10,\] which of the following cannot be a value of \[m+n\]?

    A)  25              

    B)  32

    C)  101               

    D)  50

    Correct Answer: D

    Solution :

    \[\therefore \] \[\sqrt{mn}=10\] So, \[mn=100\] \[\therefore \] (m, n) can be (1, 100), (2, 50), (4, 25), (10, 10). So, (m + n) can be 101, 52, 29, 25 and 20. Hence, 50 cannot be the value of (m + n).
