    \[\frac{4\frac{2}{21}-2\frac{13}{14}+1\frac{5}{7}\div 5\frac{1}{7}}{1\frac{7}{9}\times 2\frac{1}{48}\div 3\frac{16}{27}}\] is equal to

    A)  \[\frac{2}{3}\]

    B)  \[1\frac{1}{2}\]

    C)  \[1\frac{2}{3}\]

    D)         \[1\frac{3}{4}\]

    Correct Answer: B

    Solution :

    Given expression \[=\frac{\frac{86}{21}-\frac{41}{14}+\frac{12}{7}\div \frac{36}{7}}{\frac{16}{9}\times \frac{97}{48}\div \frac{97}{27}}\] \[=\frac{\frac{86}{21}-\frac{41}{14}+\frac{12}{7}\times \frac{7}{36}}{\frac{16}{9}\times \frac{97}{48}\times \frac{27}{97}}=\frac{\frac{86}{21}-\frac{41}{14}+\frac{1}{3}}{1}\] \[=\frac{172-123+14}{42}=\frac{63}{42}=\frac{3}{2}=1\frac{1}{2}\]
