Question

* = 0+1. As per this condition, which of the following digits should replace in the number 3*●5, so that it is exactly divisible by 3 ?​

Answer 1

Answer:

A number is divisible by 9 if the sum of its digits is divisible by 9.

Now, Sum of the digits in given number =6+7+3+0+1+2=19, which is not divisible by 9.

But, if we add 8 to this sum, it becomes 19+8=27, which is divisible by 9

So, 6730182 is divisible by 9

So, the least number is 8 which should replace for ∗ in the given number.
