MCQ

Mark the correct alternative in the following : What least value should be given to $*$ so that the number $915*26$ is divisible by $9$?

A
$1$
✓
$4$
C
$2$
D
$6$

✓

Answer

Correct option: B.

$4$

A number is divisible by $9$ if the sum of its digits is a multiple of $9$.
Sum of the given digits $= 9 + 1 + 5 + 2 + 6 = 23$
We know that multiple of $9$ greater than $23$ is $27$.
$\therefore 27 - 23 = 4$
Hence, the smallest required digit is $4$.
