A.P=100,105,110,………..,995
Therefore,a=100
d=5
a+(n-1)d=995
100+(n-1)(5)=995
(n-1)(5)=895
(n-1)=179
n=180
Therefore ,there are 180 three digit numbers which are divisible by 5

Answer 2

SOLUTION..........


Three Digits Numbers :-
100, 101, 102, ......... 999.

----- Three digits Numbers which are divisible by 5 :-
100, 105, 110, 115, 120,...............995.

The First term [a] = 100
and
The common difference [d] = 5

And
the last term [an] = 995.


Now,

an = a + [n -1 ] d

{ where; n is the no of digits which divisible by 5.}

995 = 100 + [n -1] × 5

995-100 = [n -1] × 5

[n-1] × 5 = 885

$\\ n - 1 = \frac{885}{5} \\ \\ \\ \\ n - 1 = 177 \\ \\ \\ n = 177 + 1 \\ \\ \\ n = 178 \:....... is \: the \: required \: answer...........$
