HEY!!
here is ur answer....

The A.P. will be 12, 15, 18, 21, ………….99 

We need to find n
Last term of this series is 99

So, an= 99 & a = 12
d = 15 – 12 = 3

Now,
an = a + (n – 1) d

Putting values
99 = 12 + (n – 1) (3)
99 = 12 + 3n – 3
99 = 9 + 3n
3n = 99 – 9
3n = 90
n = 90/3
n= 30

Therefore , there are 30 two digit numbers divisible by 3.

HOPE THIS HELPS YOU....
