Question

one of the two digits of a two digit number is 3 times the digit if you interchange the digits of this two digit number and add the resulting number to the original number you get 88 what is original number

Answer 1

Let the digit at tens place be 3x

The digit at ones place be x

Original Numer = 10(3x) + x = 30x + x = 31x

Interchanged Number = 10(x) + 3x = 10x + 3x = 13x

Acording to Question

31x + 13x = 88

44x = 88

x = 88 / 44

x = 2

Therefore the numbers are 13 *2 = 26

Or 31 *2 = 62

If you are satisfied please give thumbs up

Cheers!
