Question

In 4 * 672 , * should be replaced by the smallest digit and the greatest digit so that number formed is divisible by 3

Answer 1

The divisibility rule of 3 is if sum of all the digits is divisible by 3
so,
= 4 + * + 6 + 7 + 2
= 19 + *
so, to get a divisible of 3 if you add the least number 2, the answer will be divisible by 3
= 19 + *
= 19 + 2
= 21
Therefore, * = 2

Answer 2

Answer:

The correct answer will be -

The smallest digit * will be - 2

The largest digit * will be - 8

Step-by-step explanation:

Divisibility for 3 - The sum of all the digits in the number should be a multiple of 3.

The given question number is 4*672.

so, the sum of 4, *, 6, 7, and 2 should be a multiple of 3.

$= 4+*+6+7+2\\\\=19+*$

So 19+* should be a multiple of 3.

The smallest value of * is 2 because 19+2= 21 is a multiple of 3.

The greatest value of * is 8 because 19+8 = 27 is a multiple of 3.
