Problema Solution
the sum of digits of a two digit number is 13.when the number is substracted from the number formed by reversing the digits,the difference is 27.find the number
Answer provided by our tutors
The numbers that can possibly have a sum of the digits of 13 are 49, 58, 67, 76, 85 and 94.
The two of these that differ by 27 are 58 and 85.
The number is subtracted FROM the reverse of the digits, so it must be 85 - 58, so the reversed digits are 85, and the number itself is 58.
