ans-476 this is divisible by 4 & 7 ....... as when we get the LCM of 4&7 .... we 'll get 28.... dividing 500 by 28 ... remainder =24 .... we want whole no.. when we divide the no. of student by 4 & 7....
hence according to my point of view....ans=476

The L.C.M of 3,4 and 7 is 84. On dividing 500 by 84, the reminder is 20. Therefore the correct answer is 480

The L.C.M. of 3,4,7 is 84, and by dividing 500 by 84 we have reminder 80(not 20),so the number of students in the school will be 420.
