Question

How many last digit of a number should be divisible by 9 so that the whole number is divisible?

Answer 1

We cannot identify that the whole number is divisible by 9 or not. But method is,we have to do some if all digits in a number and if that sum is divisible by 9,then whole number is divisible by 9.

#example- 3343257 is number.Sum of digits is 3+3+4+3+2+5+7=27. and 27 is divisible by 9.so,whole no is also divisible by 9
