1) 27
2) 26
3) 26
4) 28
5) none

Read Solution (Total 3)

Nos divisible by 2 = (300-200)/2 + 1 = 51
Odd nos divisible by 3 = (297-201)/6 + 1 = 17
Odd nos divisible by 5 = (295-205)/10 + 1 = 10
Odd nos divisible by 15 = (285-225)/30 + 1 = 3

Hence nos divisible by 2, 3, 4 or 5 = 51+17+10-3 = 75

Answer = 101 - 75 = 26

formula l=a+(n-1)*d
so,l=297(last number divisible by 3)
a=201(first number disibile by 3)
d=3 common difference
n=number of term which is disible by 3
297=201+(n-1)*3
n=33(option 5 none)
