Answer:
71
Step-by-step explanation:
Let,
Unit Digit= X
Tenth Digit= (8-X)
therefore, the original number is= 10(8-X) + X
when the digits are interchanged,
the new number will be= (10 × X) + (8-X)
so, {10 (8-X) + X } - { (10X) + (8-X)} = 54
=> (80 - 9X) - (9X + 8) = 54
=> X = 1
So, the original number is = 71
