SSC CGL 2024 PYQ — Question 71

The correct answer is option 4 i.e. 63.

According to the given question, applying the rule of BODMAS,

$\bigg [ {(2.5+1.5)^2 \div 4\ of {1\over2}\times8-1} \bigg]$

⇒ $\bigg [ {16 \div 4\ of {1\over2}\times8-1} \bigg]$

⇒ $\bigg [ {16 \div 2\times8-1} \bigg]$

⇒ 8 × 8 - 1

⇒ 64 - 1 = 63

Hence the required answer is 63.
