Question

If we subtract 12 from any of the largest sums, by dividing by both the numbers 5325 and 6306 will be divisible which is the largest sums?​

Answer 1

Step-by-step explanation:

Let us work out with few numbers and get the answer

Let the number be 23.

Sum of digits is 2+3=5

Now, we subtract the sum of the digits from the number itself that is 23−5=18.

18 is divisible by both 2 and 9.

Similarly, Let the number be 15.

Sum of digits is 1+5=6

Now, we subtract the sum of the digits from the number itself that is 15−6=9.

9 is divisible by 9.

Hence, the sum of the digits of a number is subtracted from the number, the resulting number is always divisible by 9.
