The average temperature on Wednesday, Thursday and Friday was 25o. The average temperature on Thursday, Friday and Saturday was 24o. If the temperature on Saturday was 27o, what was the temperature on Wednesday?

• 30 degrees
  
  We + Th + Fr = 3 * 25 = 75 --- (1)
  Th + Fr + Sa = 3 * 24 = 72 --- (2)
  
  (1) - (2):
  We - Sa = 3
  We = 3 + Sa = 3 + 27 = 30 degrees

• answer is 30 degrees
  
  W+TH+f=75
  T+F+S=72
  solving these two equations we get
  W-S=3
  substitute s=27
  then w=30 degrees
