Question

in a Colony of hundred block of flats numbering 1 to 100 a school van stops at every 6th block while school bus stops at every 10th block. on which stop will both of them stop if they start from the entrance of the colony

Answer 1

60th block, nd 15th block i think must be the answer.......

Answer 2

As we see ,
Van stops on -
6,12,18,24,30,36,42,48,54,60,66,72,78,84,90,96
Bus stops on-
10,20,30,40,50,60,70,80,90,100
By observing , we find that both stop together on 30th,60th and 90th house.
There’s a relatively shorter way of doing this.
Take LCM of 6 and 10= 30
So the multiples of 30 in 1 to 100 are the answer
= 30,60,90
