SSC CHSL 2023 PYQ — Question 58

The correct answer is Option 3 i.e. $\frac{28}{135}$.

$\left ( 2\frac{1}{2}\div 1\frac{7}{8} \right )\div \left ( 9\frac{3}{8}\div 11\frac{2}{3}of\frac{1}{8}\right )$

$= \left ( \frac{5}{2}\times \frac{8}{15} \right )\div \left ( \frac{75}{8}\div \frac{35}{3}of\frac{1}{8}\right )$

$= \frac{4}{3}\div \left ( \frac{75}{8}\div \frac{35}{24}\right )$

$= \frac{4}{3}\div \left ( \frac{75}{8}\times \frac{24}{35}\right )$

$= \frac{4}{3}\div \frac{45}{7}$

= (4/3) × (7/45)

= 28/135
