SSC CGL 2023 PYQ — Question 58

The correct answer is Option 2 i.e. $\frac{3}{2}$.

51 ÷ {25 + (25 of 12 ÷ 30) - (5 ⁴ ÷ 5 of 125)}

By applying the BODMAS rule

⇒ 51 ÷ {25 + (25 of $2\over5$) - (5 ⁴ ÷ 5 of 125)}

⇒ 51 ÷ {25 + 10 - (5 ⁴ ÷ 5 of 125)}

⇒ 51 ÷ {25 + 10 - (625 ÷ 625)}

⇒ 51 ÷ {25 + 10 - 1}

⇒ $51\over34$ = $3\over2$
