Question

Sum of all the digits of a two digit number is 9. When we exchange the digits , it is

found that the resulting new number is greater than the original number by 27. What is

the two digit number?​

Answer 1

Answer:

36

Step-by-step explanation:

Let the digits be x and y.

Then, x+y = 9

the original number is 10x+y.

On reversing, we get the new number as 10y+x

The new number is greater than the old number by 27, i.e.

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

or 9y-9x = 27, or y-x = 3

and x+y = 9

Adding the two equations, we get 2y = 12 or y = 6.

Thus, x = 3.

Therefore, the original number is 36.
