Answer 1

Heya !!!

This is your answer.

We have to find how many two digit numbers are divisible by 3.

Well.....

The two digit numbers divisible by 3 are 3, 6, 9, .........., 96, 99.

So, it forms an AP with common difference of 3.

a = 3.
d = 3.
an = 99.

So.....
an = a + (n-1)d
99 = 3 + (n -1)3
3(n-1) = 96
n-1 = 32
n = 33.

Hence, 33 two digit numbers are divisible by 3.
