Question

find the small value of x,so that the number 67x51 is divisible by 3​

Answer 1

Answer:

x=2

Step-by-step explanation:

We know the divisibility rule for 3:

If the sum of the digits of a number is divisible by 3, then the number is also divisible by 3.

6+7+x+5+1  is divisible by 3

=> 19+x  is divisible by 3

Hence, x is 21-19

So,

x=2
