    A)  184                 

    B)  210

    C)  241     

    D)  425

    Correct Answer: A

    Solution :

    In figure A, \[{{12}^{2}}\,-\,{{8}^{2}}=144-64\,=\,80\] In figure B, \[{{16}^{2}}-{{7}^{2}}=256-49=207\] \[\therefore \] In figure C, \[{{25}^{2}}-{{21}^{2}}=625-441=[184]\] Hence, the lower number or the missing number is 184.
