What is the least number that must be added to 1056 so the number is divided by 25?

Given:

Given number is 1056.

To do:

We have to find the least number that must be added to 1056 so the number is divided by 25.

Solution:

We know that,

Dividend $=$ Quotient $\times$ Divisor $+$ Remainder

$1056 = 25\times42+6$

If we add ($25-6=)19$ to 1056 it becomes a multiple of 25.

Therefore, the least number that must be added to 1056 so the number is divided by 25 is 19.
