If the question is being asked by a lower-school mathematics teacher, who does not necessarily have any training or interest in temperatures, and is merely using them as a vehicle for a problem in arithmetic, then the answer is going to be connected with solving the three simultaneous equations:
(T1+T2+T3)/3=37
(T2+T3+T4)/3=34
T4=T1*4/5
Subtracting T2+T3+T4=102 from T1+T2+T3=111 you find that T1-T4=9
Thus T1*5/5-T1*4/5=9, so T1=45 and T4=36.
However, your lower-school mathematics teacher is horribly misguided in choosing vehicle for the his/her exercise in arithmetic. The point is that you cannot meaningfully take fractions or percentages of temperatures that are expressed in Celsius or Fahrenheit, because each is centred on an arbitrary offset temperature. Barry Anstern is totally correct to do the calculation in Kelvin temperature scale, but I doubt that this is the answer that your mathematics teacher was hoping for.
