On dividing 2272 as well as 875 by 3-digit number N, we get the same remainder. The sum of the digits of N is:
10
11
12
13
Answer: Option
Explanation:

Clearly, (2272 - 875) = 1397, is exactly divisible by N.

Now, 1397 = 11 x 127

The required 3-digit number is 127, the sum of whose digits is 10.

@Jatin.

Is it applicable to all problems? How did you take 3?

Jeff said:   6 years ago
Why do we subtract the two numbers, here? Please tell me.

Here is an shortcut:

= 2+2+7+2-8+7+5 = 7.

= 7+3 = 10.

We can 11*127 so we can get 1397.

But how we get 10.

2272-875 = 1397.
1397/11 = 127.
1+2+7 = 10.

Why we are factorizing 1397?
