Question

One of the two digits of a two digit number is three times the other 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 the original number? ​

Answer 1

Answer:

26

Step-by-step explanation:

let the unit place digit be x

so, the tenth place digit is 3x

now the no. will be x×10+3x=13x

reversing no.

the unit place digit be 3x

the tenth place digit is x

no.=3x×10+x=30x+x=31x

now, 31x+13x=84

so, x=84/44=2

the no. is 2×13=26
