Answer 2

Answer:

Least Value of x: 2

Step-by-step explanation:

For a number to be divisible by 3, the sum of digits of the dividend must be divisible by 3.

Then,

Sum of digits of the number: 5 + x + 4 + 7 + 8 + 1

= 25 + x

Nearest number to 25 divisible by 3 is 27 (3×9)

So,

25 + x = 27

x = 27 - 25

x = 2

Hence, the minimum value of x must be 2.
