You can put this solution on YOUR website! The sum of the digits of a two digit number is 11.
The 2 digit numbers whose sum of digits add to 11 are 29, 38, 47, 56, 65, 74, 83, 92
The original two-digit number is 5 more than 3 times the number with its digits reversed
From the above statement, it is understood that the original two-digit number is greater than the reversed number
so the number should be either 65, 74, 83 or 92
original number = 5 + 3(reversed number)
Let's apply the formula to 65, 74, 83, 92 to see which is correct
65 = 5 + 3(56) = 5 + 177 = 182 -------not correct
74 = 5 + 3(47) = 5 + 141 = 146 -------not correct
83 = 5 + 3(38) = 5 + 114 = 119 -------not correct
92 = 5 + 3(29) = 5 + 87 = 92 -------correct
92 is the number
