In an examination, 35% of the students passed and 455 failed. How many students appear for the examination?

700

Percentage of students who passed = 35%

Percentage of students who failed = 100% - 35% = 65%

Total students who appeared in the exam = 100%

Therefore,

Total students who appeared in the exam = \(\frac{ 455}{65 }\) x 100 = 700
