unit digit = x
ten's digit =y
the number =10x+y---(1)
reversing the number=10y+x----(2)
given diffrence (1) and (2) is 27
10x+y-(10y+x)=27
10x+y-10y-x=27
9x- 9y=27
divide each term with 9
x-y=3

Step-by-step explanation:
digit at unit place = x
digit at tens place = y
original number formed = 10y + x
reversed number = 10x + y
therefore ;
(10x + y) - (10y + x) = 36
