    When \[\left( \frac{1}{2}-\frac{1}{4}+\frac{1}{5}-\frac{1}{6} \right)\] is divided by \[\left( \frac{2}{2}-\frac{5}{9}+\frac{3}{5}-\frac{7}{18} \right),\] the result is

    A)  \[5\frac{1}{10}\]     

    B)  \[2\frac{1}{18}\]

    C)  \[3\frac{1}{6}\]                        

    D)  \[3\frac{3}{10}\]

    Correct Answer: A

    Solution :

    \[?=\left( \frac{1}{2}-\frac{1}{4}+\frac{1}{5}-\frac{1}{6} \right)\] \[?=\left( \frac{1}{2}-\frac{1}{4}+\frac{1}{5}-\frac{1}{6} \right)\] \[=\left( \frac{30-15+12-10}{60} \right)\] \[=\left( \frac{36-50+54-35}{40} \right)\] \[=\left( \frac{17}{40} \right)\div \left( \frac{5}{90} \right)=\frac{17}{60}\times 18\] \[=\frac{51}{10}=5\frac{1}{10}\]
