Step-by-step explanation:
Let the digit at tens place be x
Let the digit at units place be y
The number becomes (10x +y)
number formed by interchanging digits =
(10y+x)
From condition 1
x + y = 9 ....(1)
From condition 2
(10y+x) = (10x+y) + 27
i.e
9y-9x = 27
y - x = 3 ...(dividing by 9)
thus,
y - x = 3 ....(2)
Solving equation (1) and (2)
y = 6, and x = 3
Thus, we know that number is
(10x+y)
substituting the values,
10(3) + 6 => 30 + 6 = 36
Thus the number is 36
