Answer:
Step-by-step explanation:
Let us assume, x and y are the two digits of a number
Therefore, The two digit number is = 10x + y and the reverse number is 10y + x
Given:
x + y = 15 ---------1
y = 15 - x
Also given:
10x + y - 27 = 10y + x
9x - 9y = 27
x - y = 3 -----------2
Adding equation 1 and 2
2x = 18
x = 9
Therefore, y = 15 - x = 15 - 9 = 6
The two digit number is = 10x + y = (10 * 9) + 6 = 96
And the reverse number = 10y + x = (10 * 6) + 9 = 69
