SSC CPO 2022 PYQ — Question 119

The correct answer is option 3 i.e. 25/18

Given that

$6\frac{8}{15}\div \frac{7}{9}\text{ of }\left(1\frac{1}{10}+5\frac{1}{5}\right)+\frac{2}{5}\div 7\frac{1}{5}$

⇒ $\frac{98}{15}\div \frac{7}{9}\text{ of }\left(\frac{11}{10}+\frac{26}{5}\right)+\frac{2}{5}\div \frac{36}{5}$

⇒ $\frac{98}{15}\div \frac{7}{9}\text{ of }\left(\frac{11}{10}+\frac{26}{5}\right)+\frac{2}{5}\times \frac{5}{36}$

⇒ $\frac{98}{15}\div \frac{7}{9}\times\frac{63}{10}+\frac{1}{18}$

⇒ $\frac{98}{15}\div \frac{49}{10}+\frac{1}{18}$

⇒ $\frac{98}{15}\times \frac{10}{49}+\frac{1}{18}$

⇒ $\frac{4}{3}+\frac{1}{18}$

⇒ (24 + 1)/18 = 25/18
