How many students did secure First class in a class of 50 students ?

I.Double the number of first class students secured second class and all the remaining students failed

II.Number of students failed was twice the number of first class students in the class

Only I

Only II

Both I and II

Either I or II

Neither I or II

From I:
No of Students Failed = 50-3x
From II:
No of Students Failed = 2x
2x = 50-3x
5x=50
X = 10
Hence, option 3 is the correct answer.
