Question

if 51 z3 is multiply of 3 where Z is a digit what might be the value of Z​

Answer 1

Given that 51z3 is a multiple of 3 , so we have to find the possible values of z.

Divisibility rule of 3 :

For being a multiple of 3 the sum of the digits of the number must be divisible by 3.

So ,

5+1+z+3 = 9+z

Hence we can determine the possible values of z.

The possible values of z = 0,3,6,9

The Answer so required is 0,3,6,9.

Answer 2

The Answer is required 0,3,6,9.
