SSC GD 2021 PYQ — Question 54

The correct answer is option 4 i.e. -107/48.

$(\frac{7}{16}\div 10\frac{1}{2} \ of \ 7\frac{1}{5})\times 3\frac{3}{5}-1\frac{1}{3}\times 1\frac{1}{8}\div\frac{1}{2}+\frac{3}{4}$

= (7/16 ÷ 21/2 of 36/5) × 18/5 - 4/3 × 9/8 ÷ 1/2 + 3/4

= (7/16 ÷ 378/5) × 18/5 - 4/3 × 9/8 ÷ 1/2 + 3/4

= (7/16 × 5/378) × 18/5 - 4/3 × 9/8 ÷ 1/2 + 3/4

= 5/864 × 18/5 - 4/3 × 9/8 ÷ 1/2 + 3/4

= 5/864 × 18/5 - 4/3 × 9/4 + 3/4

= 1/48 - 3 + 3/4

= (1 - 144 + 36)/48

= -107/48
