Question

The sum of the digits of a two digit number is 7. If the number formed by reversing the digits is

less than the original number by 27, find the original number.

Answer 1

Answer:

The no. Is 52.

5+2=7

52-25=27

Answer 2

Step-by-step explanation:

Let the digits be x and y

x +y =7

10x + y =10y +x +27

9x - 9y=27

x-y =3 equation 1

x+y=7 equation 2 (on adding both equations )

2x=10

x=5

y=2 original number is 52 -27 =25
