91 since the ones digit is 8 less than 9 and the two digits, 9+1 = 10, a two-digit number.
One way to do this is multiply 8x3=24 so 24 has both as factors. Now multiply it by 10 and you have 240. That is a 3 digit number and sill has 8 and3 as factors.
There is no such two digit number. If the first digit is x and the second is y, then the number is 10x + y, its digit reverse is 10y + x, and: 10x + y + 8 = 10y + x → 9x + 8 = 9y → 9x + 8 = 18x → 9x = 8 → x = 9/8 BUT x must be a whole number.as x is a digit 1-9. ergo the problem as stated has no solution.
67 and 8 are factors of 536
16 (1, 2, 4, 8, 16) and 81 (1, 3, 9, 27, 81).
