Given: Marks scored by Nilesh = 188 Minimum marks required to pass an exam = 35% of maximum marks Calculation: Let, 'x' be the maximum marks. We know, Nilesh scores 188 marks and he fails by 22 marks. This means Nlilesh requires 22 more marks to pass an exam. ⇒ 188 + 22 ⇒ 210 Now, Nilesh has to score at least 35% of maximum marks to pass an exam. ⇒ 35% of x = 210 ⇒ (0.35) × x = 210 ⇒x=(
210
0.35
) ⇒ x = 600 Therefore, the maximum marks of an exam is 600. Hence, the correct answer is 600.
