Answer 1

Answer:

85

Step-by-step explanation:

Let the numbers of 2 digit number be x and y and the number be 10x+y

x-y=3

y=x-3

10x+y+10y+x=143

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

22x-33=143

22x=143+33

22x=176

x=8

y=x-3

y=8-3

y=5

Therefore the original number=10x+y

                                                  =10*8+5=85
