Let the two-digit number be 10a + b a + b = 12 --- (1) If a>b, a - b = 6 If b>a, b - a = 6 If a - b = 6, adding it to equation (1), we get 2a = 18 => a =9 so b = 12 - a = 3 Number would be 93. if b - a = 6, adding it to the equation (1), we get 2b = 18 => b = 9 a = 12 - b = 3. Number would be 39. There fore, Number would be 39 or 93.
