Question

10. The digits of a two-digit number differ by 3. If the digits are interchanged and the
resulting number is added to the original number, we get 143. What can be the original
number?
​

Answer 1

Answer:

85 or 58

Step-by-step explanation:

let the number be 10x+y

new number=10y+x

10x+y+10y+x=143

11(x+y)=143

x+y=13

x-y=3

2x=16

x=8

y=5
