    A)  2.833              

    B)  0.28                

    C)  0.000028         

    D)         0.00028

    Correct Answer: A

    Solution :

    We have, \[\frac{2\frac{5}{4}-5\frac{1}{6}+3\frac{1}{3}}{0.087+0.3717\div 0.9}~\] \[=\frac{\frac{13}{4}-\frac{31}{6}+\frac{10}{3}}{0.087+0.413}~=\frac{\frac{39-62+40}{12}}{0.5}\] \[=\frac{12}{0.5}=\frac{17}{6}=2.833~~~\]
