80=8*10=16*5
since 5 is present then last digit must be either 5,0 then the number is divisible by 5
since number must be divisible by 2 it must be a even number so y=0 is the only case possible
in order to divisible by 8 its last 3 digits must be divisible by 8 so 653x0/80 = 653x/8 so last three digits 53x must be divisible by 8 so 8*67=536 (53x=536)
so x=6 and y=0
x+y=6
