Question

2. The total no. of numbers that are divisible by 2 or 3 between 100 and 200(both inclusive) are

Answer 1

see there are 100 102 104............200 total 51 no.s divisible by 2
there are 102 105 108...........198 total 33 no.s
that totals 84 no.s but these 84 numbers also includes no.s which are divisible by both 2 and 3 and have been included twice like 102 108 114 120........198 total 17 no.s so they have to be removed once
84-17=67 is the write answer.ask if any doubt
