SSC GD 2021 PYQ — Question 58

The correct answer is option 3 i.e.  $-\frac{169}{75}$

$2\div\frac{1}{5} \ of \ (4+4\div2)+[\frac{1}{2} \div\frac{25}{4}-4].$

2 ÷ $\dfrac{1}{5}$of (4 + 4 ÷ 2) + ($\dfrac{-98}{25}$)

= 2 ÷ $\dfrac{1}{5}$ of 6 $\dfrac{-98}{25}$

= 2 ÷ $\dfrac{6}{5}$ - $\dfrac{98}{25}$

= $\dfrac{5 × 2}{6}$- $\dfrac{98}{25}$

= -$\dfrac{169}{75}$
