Question

the sum of a 2-digit number is 11 if 27 is added to the number we get a new number that is also formed by interchanging the digits of the original number find the number​

Answer 1

Answer:

Let tens digit number be x and ones digit number be y

So original number is 10x+

According to question

x+y=11.

x=11-y. ------(1)

10x+y+27=10y+x. --------(2)

Using (1) in (2)

10(11-y)+y+27=10y+11-y

110-10y+y+27=9y-11

137-9y=9y-11

18y=126

y=7

x=11-7=4

So the number is 47.

Hope this helps!
