Answer» Let the digits be x and y. Then, x+y = 9 the original number =10x+y. Reversed= 10y+x The new number is greater than the old number by 27, i.e. (10y+x) - (10x+y) = 27 9y-9x = 27y-x = 3 x+y = 9 Adding the two equations, we get 2y = 12 or y = 6. Thus, x = 3. Therefore, the original number is 36.

Answer»

Let the digits be x and y.

Then, x+y = 9

the original number =10x+y.

Reversed= 10y+x

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

(10y+x) - (10x+y) = 27 9y-9x = 27y-x = 3 x+y = 9

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

Thus, x = 3.

Therefore, the original number is 36.
