37
33
35
36​

Answer 1

only 33 and 36 because 3 + 3 is 6 and 3 + 6 is 9 and six and nine are divisible by 3 so 33 and 36 will be divisiblby 3 and 8 can't be divide any of these numbers.

Hope it is helpul

thanks for the question

Answer 2

Answer:

We know, first two digit number divisible by 3 is 12 and last two digit number divisible by 3 is 99. Thus, we get

12,15,18,...,99 which is an AP

Here, a=12,d=3

Let there be n terms. Then,

a

n

=99

a+(n−1)d=99

12+(n−1)3=99

n=29+1=30

Therefore, two digit numbers divisible by 3 are 30.
