Question

In an examination, 65% of total students is passed. If the number of failure is 420, the total number of student is?

Answer 1

Answer: 1200

Explanation:

⇒  Let total examines is x.

⇒  65% of total examines has passed.  

⇒  student failed =100%−65%=35%

Then, 35% of examines have failed.

⇒  Number of failures is 420

∴  35% of x=420

∴  35/100 x x = 420

 

​x=   420×100/35

​∴  x=1200

Thus, Total number of examines are 1200.
