AB° Celsius ≅ BA° Fahrenheit
2*CD° Celsius ≅ DC° Fahrenheit
How much is A+B+C+D?
Rem: XY denotes 10*X+Y
F = 9/5*C-32
For both to be integers C must be a multiple of 5. To be two digits then F must begin with 5.
15 degrees C = 59 degrees F. Which doesn't fit.
Likewise with the second equation.
2*15 degrees C = 86 degrees F. Which doesn't fit.
Is this problem possible or am I missing something?
