    C)  45       

    D)  30

    E)  20

    Correct Answer: D

    Solution :

     \[\left( \sqrt{2704}+78 \right)\div 13+\frac{?\times 70}{100}=31\] \[\Rightarrow (52+78)\times \frac{1}{13}+\frac{?\times 7}{10}=31\] \[\Rightarrow \,\,\frac{130}{13}+\frac{?\times 7}{10}=31\] \[\Rightarrow \,\,\frac{?\times 7}{10}=31-10=21\] \[\Rightarrow \,\,?=\frac{21\times 10}{7}=30\]
