SSC CHSL 2021 PYQ — Question 63

The correct answer is option 4 i.e. 8

$(5\frac{5}{6}\div3\frac{1}{2}of\frac{10}{21})\div(\frac{3}{4}\div1\frac{1}{2}of\frac{4}{5}-\frac{4}{5}\times\frac{1}{2})of\frac{35}{18}$

⇒ $(\frac{35}{6}\div\frac{7}{2}of\frac{10}{21})\div(\frac{3}{4}\div\frac{3}{2}of\frac{4}{5}-\frac{4}{10})of\frac{35}{18}$

⇒ $\frac{7}{2}\div(\frac{5}{8}-\frac{4}{10})of\frac{35}{18}$

⇒ $\frac{7}{2}\div\frac{7}{16}$ = (7/2)*(16/7) = 8
