- 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 - 9 years agoHelpfull: Yes(3) No(1)
- 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
