Answer:
     A union B = 600
     A Intersection B = 100
       Set A = 150
       Set B = 225,
Therefore , Number of Students who neither knows Hindi nor English = A UNION B  -  (SET A + SET B - A INTERSECTION B )
                         = 600 - (150+225 - 100) = 600 - 375 = 325

Hope this helps You!!!
