Question

the digits of a 2 digit number differ by 3. ifhe digits are interchanged and the resulting new number is added to the original number, you get 143. what canbe the original number​

Answer 1

Let, tens digit number be x

ones digit number be (x-3)

Original number = {10x+(x-3)}

After interchanging the digits, the new number

= {10(x-3)+x}

ATP

{10(x-3)+x}+{10x+(x-3)} = 143

=) (10x-30+x)+(10x+x-3) = 143

=) 10x-30+x+10x+x-3 = 143

=) 22x = 143+30+3

=) 22x = 176

=) x = 8

Ans:-Original number = {(10×8)+(8-3)} = (80+5) = 85
