Question

If 5*6 is exactly divisible by 3
then the least value of x is​

Answer 1

5×6=30

30÷3=10

so the least value of x is 1

Answer 2

Answer:

We know that the sum of the digits of a number is divisible by 3 then the whole number is divisible by 3

5+x+6 = multiple of 3

11+x= 0, 3, 6, 9….

11+x= 12

∴ x=12-11 = 1

The least value of x is 1
