Question

if 3076z is multiple 5 where z is a digit what could be the value of z? ​

Answer 1

Answer:

Since 31z5 is a multiple of 3 ,the sum of its digits  must be a multiple of 3 i.e. 3+1+z+5=9+z

Hence 9+z is a multiple of 3

Since z is a single digit which can value from 0 to 9

Possible values of z will be,

9+0=9

9+3=12

9+6=15

9+9=18

Thus, there can be four possible values i.e. 0,3,6 or 9
