The sum of the digits of 2digit number is 8 .when 18 is added to the number ,the digits of the sum obtained are reverse of those of the number .find the original number

Answer 1

Answer:

Sum of two digit number is 8

so the number could be 17 or 26 or 35.

Another clue given is, when 18 is added to the number, the digits interchange their position.

17+18= 35, 26+18=44 (digits are not nterchanged)

35+18= 53 digits interchanged.

Therefore, the original number is 35.
