Let the ones number be x.
Tens place number = (12-x)
Value of the number = 10(12-x) + 1(x)
= 120-10x+x
=120-9x
On interchanging,
Ones place = (12-x)
Tens place = x
Value = 10(x)+1(12-x)
= 10x+12-x
= 9x+12
ATQ, (120-9x)-(9x+12) = 54
=> 120-9x-9x-12 = 54
=> 108-18x = 54
=> -18x = 54-108
=> x = -54/-18
=> x = 3
Ones place digit = x = 3
Tens place digit = 12-x = 12-3 = 9
Digit = 93
There is your answer
