Let the digit at tens place be 3x

The digit at ones place be x

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

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

According to Question,

31x + 13x = 88

44x = 88

x = 88 / 44

x = 2

Therefore the numbers are 13 *2 = 26

Or 31 *2 = 62

Hi,

There is some question error because anything + anything = anything

So the instead of "it yet".. Tell me a number

OK lets take the number 88

It's given that

The first digit = 3 times the second digit

Therefore
Let 1st digit = x
And 2 nd digit = y

Therefore
x = 3y

Now
It's given that 10x + y + 10y + x = 88
11x + 11y =88
11(x + y) = 88
x + y = 8
3y + y = 8
4y =8
y= 2

And,
x = 3(y)
x = 3(2) = 6

So,
The 2 number = 62, 26

Bye
