If x and y are the two digits f the number 653xy such that this number is divisible by 80

since 653xy divisible by 80, 80 have 0 so, y=0.Remain 653x
as we know for divisible of 8 last three digits of a whole number are divisible by 8.
53x to be divisible , x have to be 6.
So answer is 6+0=6

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.

number divisible by 80 means divisible by 8 and 10
if number divisible by 10 means unit digit contain 0,so y=0
if number divisible by 8 means last 3 digits divisible by 8,so x=6

to divide with 80 last number would be '0'.so y=0 to find the x divide with 8 x value would be 6

65360 is divisible by 80 so x+y=6+0 which is equal to 6 so answer is 6

If x and y are the two digits f the number 653xy such that this number is divisible by 80, then x+y is equal to:

(i) 2
(ii) 3
(iii) 4
(iv) 6

Answer is :
