if the number 452xy be completely divisible by 60, the value of (x+y) is ?

options are :-

1)8

2)6

3)3

4)1

5) none of these

according to my answer sheet the answer is 4th option that is 1, but i am not satisfy.

... *... *...

my opinion:-

60 = 6*10

then last digit of 452xy is 0 it means y is 0. then x must be a number by that 452xy completely divisible by 60. I think x will be 4. so (x+y)= (4+0)= 4

Answer is 5th option None of these.
