Clock

What time is now, if the time elapsed after noon is 2/10 of time that elapses before midnight?

Result

hh:mm = 14:00 Wrong answer

Solution:

x=12+t t=210(12−t)  t=12⋅22+10=2 x=12+t=14=14:00x = 12 + t \ \\ t = \dfrac{ 2}{ 10}(12-t) \ \\ \ \\ t = \dfrac{ 12 \cdot 2 }{ 2+ 10} = 2 \ \\ x = 12 + t = 14 = 14:00
