SSC GD 2021 PYQ — Question 73

The correct answer is option 2 i.e. $\frac{1}{30}$

Concept used:

BODMAS rule

Calculations:

⇒ $\dfrac{9\div[{5-5\div(6-7)\times8+9}]}{4+4\times4\div4\ of\ 4}$

⇒ $\dfrac{9 \div [5 - 5\div (-1) \times 8 + 9]}{4 + 4\times 4 \div (4 \times 4)}$

⇒ $\dfrac{9 \div [5 + 40 + 9]}{4 + 4 \times 4 \div 16}$

⇒ $\dfrac{9 \div 54}{4 + 4 \times \dfrac{1}{4}}$

⇒ $\dfrac{\dfrac{1}{6}}{4 + 1}$

⇒ $\dfrac{1}{30}$
