SSC CPO 2024 PYQ — Question 103

The correct answer is option 1 i.e.  $2\frac{43}{120}$

⇒  $5\frac{1}{4} - [3\frac{1}{2} -$ { $\frac{5}{6} - (\frac{3}{5}$ × $\frac{1}{10} ÷ \frac{4}{15} )$ }] 

By applying BODMAS rule:-

⇒ $\frac{21}{4}$ - [$\frac{7}{2}$ - { $\frac{5}{6} - (\frac{3}{5}$ × $\frac{1}{10} ÷ \frac{4}{15} )$ }] 

⇒  $\frac{21}{4}$ - [$\frac{7}{2}$ - { $\frac{5}{6}$ -  $\frac{9}{40}$}]

⇒  $\frac{21}{4}$ - [$\frac{7}{2}$ - $\frac{73}{120}$]

⇒  $\frac{21}{4}$ - $\frac{347}{120}$

⇒ $\frac{283}{120}$

⇒ $2\frac{43}{120}$
