Answer:
The original number is 96
Step-by-step explanation:
Let the digit in units place be y
Let the digit in ten's place be 10x
Number formed=10x+y
Number for by reversing the digits=10y+x
According to the problem:
x+y=15 ---i
(10x+y)-(10y+x)=27
=> 10x+y-10y-x=27
=>9x-9y=27
=>9(x-y)=27
=>x-y=3------ii
Adding the two equations i and ii
x+y+x-y=18
=>2x=18
=>x=9
Substituting value of x in equation i;
x+y=15
=>y=15-9
=>y=6
The number=
10x+y
= 10*9+6
96
