Step-by-step explanation:

Let the two numbers be x and y .

The two digit number formed will be 10x+y

on reversing the digits, the number will become 10y+x

10x+y+10y+x=55

11x+11y=55

11(x+y)=55

x+y=5

The possible values of y are 0,1,2,3,4

When y=0

x+0=5

=> x=5

The number is 50

Similarly The other possible values of the two digit number are 14, 23, 32, 41

The one fitting right to the condition in the question is 23.

The number formed by reversing the digits is 32.

And 23+32=55
