- If to make divisible by 225 then it must be divisible by 25and 9 9(factorise in two known divisibility test)
to divisible by 9 sum of all digit must be divisible mean
2+0+1+7+A+B+5=12+A+B and then if you add 12+6=18 then it is divisible
also 12+15=27 also divisible so use hit and trial
4+2=6
8+7=15
and rest are not going to satisfy only two
