Question

578x4 is divisible by 3 ,then find the least value of x

Answer 1

Answer:

x=3

Step-by-step explanation:

5+7+8+x+4

24+x

We have to add any no. in place of x to make it multiple of 3 so we will add 3 in it to make it 27 because 3×9 is 27

24+3=27

the no. will be 57834

hope it will help you

Answer 2

Answer :

As we know that if the sum of the digits of the given no. Is divisible by 3 then the given no. Is also divisible by 3.

So,

sum = 5 + 7 + 8 + x + 4

= 24 +x

There fore the value of x will be

X = 3

So the total sum including x will be 27 which is divisible by 3.

Hence, the no. Will be 57834.
