Three digit numbers starts from 100&ends at 999
smallest three digital number which is divisible by 12is 108
if repeatedlyadd 12 with 108....
1st get 108+12=120
120+12=132
........
until reach 999,108is divisible by 12,then (108+12×n) will also divisible by 12.
At last,108+12×n is equal to 999
108+12n=999
12n=891
n=891/12 =74.25
so 74.25+1=75.25 number of three digit number s are divisible by 12.
