In an examination, 65% of the total examines passed. If the number of failures is 420, the total number of examines is A. 500B. 1000C. 1200D. 1625

Answer»

Let the total number of examines = Z 

Percentage of examines failed = (100 – 65) % = 35% 

∴ 35% of Z = 420 

⇒ Z × 35/100 = 420 

⇒ Z = 420 × 100/35 

⇒ Z = 12 × 100 

⇒ Z = 1200
