Question

In each of the following number replace X by the smallest digit to make it divisible by 3 question 7×5631

Answer 1

Answer:

we should know that a no divisible by 3 have sum of all digits divisible by 3 I.e.7+x+5+6+3+1=22+x

so =22+2

=x=2

Step-by-step explanation:

Divisibility rule for 3 states that a number is completely divisible by 3 if the sum of its digits is divisible by 3 i.e., it is a multiple of 3

Sum of digits =7+x+5+6+3+1

                     =22+x

If we take x=2,5,8 the no. will be divisible by 3.

Taking small value x=2
