Question

In the following numbers, replace * by the smallest number to make it divisible by $3$

$53*46$

Answer 1

We know that,

For divisible by $3,$ the sum of the digits should be divisible by $3$

Sum of digits of $53*46=5+3+*+4+6=18$, which is already divisible by $3$

So, * will be $0$

Hence, replace * by $0$.
