Answer:
Let us assume that one of the digit of the two digit number is X, then problem the other number will be (8 - X)
Let us assume that one of the digit of the two digit number is X, then problem the other number will be (8 - X)From problem we get that, if we add 27 to the number the digits get interchanged and also since the number is a two digit number then X will in tens place (7 - X) will be in ones place.
