SSC CHSL 2024 PYQ — Question 53

The correct answer is option 1 i.e. $\frac{77}{5}$.

$10+ 3 \frac{3}{5} \div \left[2 \frac{2}{3}\div \left\{ 7 \frac{1}{6}- \left(2 \frac{1}{2} + \frac{2}{3}\right)\right\}\right]$

⇒ 10 + $3\frac{3}{5}$ ÷ [$2\frac{2}{3}$ ÷ {$7\frac{1}{6}$ - ($\frac{15 + 4}{6}$)}]

⇒ 10 + 18/5 ÷ [8/3 ÷ {43/6 - 19/6}]

⇒ 10 + 18/5 ÷ [8/3 ÷ 4]

⇒ 10 + 18/5 ÷ [8/3 × 1/4]

⇒ 10 + 18/5 × 3/2

⇒ 10 + 27/5

⇒ (50 + 27)/5 = 77/5
