Difference = Sum of digits at odd places – Sum of digits at even places
= (1 + 5 + 9 + 4) – (2 + 4 + 3)
= 19 – 9 = 10
In 10, we must add at least 1 so that it is divisible by 11. So x = 1
Also, the sum of digits of 1254934
= 1 + 2 + 5 + 4 + 9 + 3 + 4 = 28
1254934 will be divisible by 3, after adding y, if the value of y is – 1.
So, x = 1 and y = – 1 is the set of values for x and y.
