Answer 1

Good Morning

Any Two digit number say ( ab ) can be written like this.

10a + b

And if we interchange the digits ( ba ) the new number becomes 10b + a .

Q.NO 1:-

let the two digit number be xy

According to the given question

x = 3y ... Equation ( i )

And

10x + y + 10y + x = 88

11x + 11y = 88

x + y = 8 ... Equation ( ii )

Now, put value of y in Equation ii we have

3x + x = 8

4x = 8

x = 2 And y = 6

So, the two digit number is 26
