Question

Out of a class of 150, one-third opted for Sanskrit, two-fifth opted for Hindi and
rest opted for French. Find how many opted for French?​

Answer 1

Total number of students in class = 150

Number of students opted for sanskrit = 150/3 = 50

Number of students opted for Hindi = 2*150/5 = 60

Then,

Number of students opted for French = 150 - 50 - 60 = 40
