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:

62

Step-by-step explanation:

Let one of the digit be x

then the other digit is 3x

Original number = 10(3x) + 1(x)

= 30x + x

= 31x

Number obtained after interchanging the digits

= 10(x) + 1(3x)

= 10x +3x

=13x

sum of these two numbers = 88

31x + 13x = 88

44x =88

x =2

3x = 6

Original number is 62

Hooe it is clear...
