Question

What least number should be added to $1056$, so that the sum is completely divisible by $23$?

• A. $1$
• B. $2$
• C. $4$
• D. $8$

Answer 1

Answer: (B)

$2$

$\Rightarrow$ When $1056÷23$, we get $21$ as a remainder.

$\Rightarrow$ So, $23-21=2$ must be added to 1056 in order to sum completely divisible by 23.

$\therefore$ $1056+2=1058$

$\therefore$ The least number should be added to 1056, so that the sum is completely divisible by 23 is $2$.
