SSC CGL 2024 PYQ — Question 61

The correct answer is option 1 i.e. 70.

the Total Marks

Since R misses the target by 35%,

his actual percentage score = 85% − 35% = 50%

Thus, 450 marks correspond to 50% of the total marks. 

Let the total marks = x

⇒ 50% of x = 450 

⇒ $\frac{50}{100} \times x = 450$

⇒ x = 450 × 50/100 ​ = 900

R should score = 85% of 900 = $\frac{85}{100} \times 900 = 765$

The increment needed = 765 − 450 = 315

The percentage increase in marks = $\frac{315}{450} \times 100$

⇒ $\frac{7}{10} \times 100 = 70\%$
