Let the unit digit = x
tens digit = y
2 digit number above 60 ,
xy + 60 =_____1
Sum of digit between is 14
x + y = 14________2
Difference between digit is 2
x - y = 2_________3
y - x = 2_________4
By solving equation 1 and 2
We get y = 6
and x = 8
If we solve by equation 4 then the digit comes in negative .
x is unit and y is tens digit
So that number is 86
