SSC CPO 2022 PYQ — Question 147

The correct answer is option 2 i.e. $6\over5$.

√[36 ÷ 30 of [25 × 4 ÷ 4 of[29 - (8 - 11) ÷ (9 × 5 ÷ 5 of 3)]]

= $\sqrt{36 ÷ 30\, of[25 × 4 ÷ 4\,of [29 -(-3) ÷ (9 ÷ 3)]]}$

= $\sqrt{36 ÷ 30\, of[25 × 4 ÷ 4 \,of(29 + 1)]}$

= $\sqrt{36 ÷ 30\, of[25 × 4 ÷ 120]}$= $\sqrt{36 ÷ 30\, of\frac{5}{6}}$= $\sqrt{36 ÷ 25}$ = $6\over5$
