Answer 2

Answer:

58 and 85

Step-by-step explanation:

As te digits of two digit number differ by

3

, there are two possibilities. One the unit digit be

x

and tens digit be

x+3

, and two that tens digit is

x

and unit digit is

x+3

In first case, if unit digit be

x=3

and tens digit is

x

, then number is

10(x+3)+ x=11x+30

and on interchanging numbers, it will become

10 x +x+3=11x++3.

As sum of numbers is

143

, we have

11 x +30+11 x +3=143

or

22 x =110

and

x = 5

and number is

58

Observe that if it is reversed i.e it becomes

85

, then sum of two again will be

143

Hence number is

58
