    A)  0.075                          

    B)  0.3                  

    C)  1.3                  

    D)         1.375              

    Correct Answer: B

    Solution :

    Let the missing number be X. Then we have, \[2.25\div 9+1\frac{1}{8}-(6.5\times 0.2)=X\times \frac{1}{4}\] \[\Rightarrow \]\[2.25\div 9+\frac{9}{8}-1.3=X\times \frac{1}{4}\] \[\Rightarrow \]\[0.25+1.125-1.3=X\times \frac{1}{4}\] \[\Rightarrow \]\[0.075=X\times \frac{1}{4}\Rightarrow X=0.075\times 4\] \[\Rightarrow \]\[X=0.3\]
