Question 447881
Let the ten's be x, then its units are x+5 and the sum of digits is x+x+5=2x+5 and the value of a number will be:10x+x+5=11x+5. Since its value equals 3 times the sum of the digits we write the equation:

{{{11x+5=3(2x+5)}}}=>{{{5x=10}}}=>{{{x=2}}}.The units are 2+5=7.

Answer: The two digit number is 27.
