80=2*5*8
Since 653xy is divisible by 2 & 5 both .so y=0
Now,653x is divisible by 8.so 13x should be divisible by 8
This happens when x=6
X+y=6+0=6

A number is divisible by 80 if it is divisible by 5 and 16.
For a number to be divisible by 5, unit digit must be either 0 or 5.
For a number to be divisible by 16 ,number formed by last 4 digit
should be divisible by 16.
Since a number ending with 5 can not be divisible by 16 so
unit digit i.e. y will be 0.
Now we are left with following options:
65300,65310,65320,65330,65340,65350,65360,65370,65380,65390

65360 will be divisible by 80.
