In an examination, 65% of the total examinees passed. If the number of failures is 420, then the total number of examiners are?
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
∴ 35x/100 = 420
x=(420 * 100)/35
∴ x=1200
Thus, Total number of examines are 1200.
