Question

The number 2x3456y is divisible by 6. What are the possible value of x and y? Give reasons.

Answer 1

the multiples of 6 are 6,12,18,24.........

so in the number 2x if x is 1 the number is not divisible
if x is 2 the number is not divisible

if x is 3 the resulting number is 6 which is divisible by 6.
hence the possible value of x is 3

in the number 3456y if y is 1 the number is divisible by 6
hence the possible value of y is 1
