Question

Fill in the greatest digit to make the number divisible by 3? - 53 ( ?)

Answer 1

The test for divisibility of 3 states that,
For a number to be divisible by 3 the sum of digits must be divisible by 3
So, for the blank value,
_53, Let us consider the digit to be x

So x+5+3 should be divisible by 3
x+8 should be divisible by 3

Now ,let us start by taking the greatest single digit number 9
So 9+8=17 which is not divisible by 3
So now let us take 8
8+8=16 which is again not divisible by 3
So, let us take number 7
7+8=15
So 15 is divisible by 3
So the value of x is 7

Hence the number is 753
