Answer:
answer is 36
Step-by-step explanation:
let the two digit number be 10x +y
so, x +y = 9 (equation 1)
given that the number obtained by interchanging the digit exceeds the given number by 27
10y +x = 10x + y +27
9x-9y = -27
x-y = -3 (taking 9 as common) (equation 2)
adding equation 1 and 2
x+y =9
x-y= -3
2x = 6
x=3
3+y = 9
y = 6
the number is 10x+y is 36
