let the digit be x
let the other digit be y

a/q,
x-y=5---(i)

the no. is (10x+y)

if we interchange the digits...
the new no. is (10y+x)

sum of the new no. and old no.= 99

10x+y+10y+x=99
11x+11y=99
x+y=9----(ii)

(ii)-(i)
x+y=9
x-y=5
----------
2y=4
y=2

x-y=5
x=5+y
x=5+2
x=7

the original no. =72

Hope it helps u...
If yes, mark brainliest...
Have a gr8 day ahead...
