First find the largest 3 digit no.divisible by 3 that is 999 .....
Now,
a+(n-1)d=999...........1
Where...,
a=102(because it is the smallest 3 digit no. Divisible by 3)
d=3(because we are following 3 table as per the question)
Now u have to substitute the no. In.....1 and find n......which is the answer and it is always a whole no.
