Question

Sum of digits of a two digit number is
12. When we interchange the digits, it is
found that the resulting new number is
smaller than the original number by 36.
What is the original number?​

Answer 1

Answer:

84

Step-by-step explanation:

x+y= 12_______1

10x+y-10y-x=36

9(x-y)= 36

x-y= 4. _______2

solving eq 1 and 2 we ger

x=8

y=4

thus no is 10x + y=80+4= 84
