Answer:
58 or 85
Step-by-step explanation:
As the digits of two digit number differ by 3 there are two possibilities.
One the unit digit be X
The tens digit could be 3
put them together is:
x+3
and two that tens digit is
x
and unit digit is
x+3
In first case, if unit digit could be x
and tens digit could be
x+3
then it'll be
10(x+3)+x=11x+30
When you multiply 10 with the X and 3 it'll become:
10x+x+3=11x+3
As sum of numbers is
143
11x+30+11x+3=143 or
22x=110
and
x=5
so number is 58
Observe that if it is reversed i.e it becomes
85
Then sum of two again will be
143
Hence number can be 58 or 85
