Solution
4x573y will be divisible by 72
to divide that no it should be divided by 9 and 8 both
- for divisibility by 8 the last three digit will be divided by 8 the last digit is y so y will be 6
- but for divisibility by 9 the sum of all digits divisible by 9
- y = 9
- Sum of digits = 4 + x + 5 + 7 + 3 + 6 = 25 + x, so x = 2
- x+y = 6+2 = 8
