• monday+tuesday+wednesday=3*27=81
  tuesday+wednesday+thursday=24*3=72......(2)
  thursdy=2/3monday
  ==>tuesday+wednesday=81-monday=81-3/2thursday(from 2)
  81-3/2th+th=72
  81-th/2=72
  th=18

• mon+tue+wed=27*3;
  tue+wed+thur=24*3;
  mon-thurs=(27*3)-(24*3)=9
  mon-(2/3(mon))=9
  mon=27...

• (M+T+W)/3=27
  (T+W+Thu)/3=24
  Let T+W=X,
  then we have
  => M + X = 27x3
  => X = 27x3 - M
  Also X + Thu = 24x3 or X = 24x3 - Thu
  =>Equating both the values of X, we get,
  => 27x3 - M = 24x3 - Thu
  Now use the fact that Thu = (2/3)M i.e. Thu=2M/3 put in above equation, and we'll get
  => 27x3 - M = 24x3 - 2M/3
  => M/3 = 3x3 (re-arranging)
  => M = 27 degree Celcius
