guys if u find the previous way to be tedious let me give u a more simple way of solving:
if 35% of students passed then definitely 65% would have failed. rite!
let the total no of students be x.
so 65% of x=455 (i.e no of students failed)
65/100 x X = 455
SO X=455x(100/65)=700 students.
hope this s useful..!! enjoy!! all the best!!

TO solve this puzzle lets go by the options:
a) 490 students appeared for examination.
if so then 35% of them passed. so 35% of 490 s some decimal no so this option s not possible.
llly for options c), d) too.
b) 700 students appeared for examination. so 5% of them passed means 35% of 700 which s 245. so if we subtract the no of students passed i.e 245 from 700 we get 455 which gives the no of students failed. so option b) is the answer..
hope its useful.. enjoy!!! all the best!!!

ok! i am going to solve this question by using concept of percentage(basically i am going to use actual meaning of percentage )

35% pass means 35/100=7/20 pass , means if total number of student was 20, then only 35% of 20 that is 7 passed ,means 20-7=13 failed , if 13 failed then 7 pass we know , means if 1 failed then 7/13 pass ,but according to the question 455 failed so 455*(7/13) will be passed after solving we get 245 (passed student ),now we need total student so just add (passed +failed) =245+455=>700 Ans.

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.
