Answer / marvin
Total no of students failed = 65% (100-35% who passed)
so
455/65=7, which is equal to 1% of total strength.
Total no of students passed is 35%, So
7*35=245.
So Total Students is equal to
245+455= 700.

Answer / varun dubey
let there are n students .
35% are passed.
therefore (100-35)% =65% students are failed.
65*n/100=455.
by solving this equation we get n=700.
Hence,there are 700 students.

Answer / amruta
100 percent students appeared for exam
from which 35 % passed
which means (100-35) = 65% failed
No. of students failed = 455
65% = 455
then 35% = ?
so by cross multiplication
? = (455/65)* 35
? = 245
so we got 35% is 245
Therefore total no. of students appeared for the exam = 245+455 = 700

Answer / naveen singh
Let no. of student attempted exam = x
Total student failed = 455
% of student passed = 65% (100%-35%)
Therefore:
65% of x = 455
65/100 of x = 455
x = 455*100/65
x = 700
so, 700 is the total number of student attempted the exam.

Answer / pardeep kumar
Let total No. Of students =x
35% students passed of total students. Mean 35% of x
x =35% of x + 455
x - 35% of x = 455
65% of x = 455
X = 455*100/65
x= 700
