Average temp. Of Monday, Tuesday, wed and Thursday was 38 degree C. And of Tuesday, Wednesday, Thursday and Friday was 40 degree C. Temperature on Monday was 30.Then what was temp on Friday?

• (mon+tue+wed+thur)/4=38
  mon+tue+wed+thur=152,mon=30
  tue+wed+thur=122-------1
  (tue+wed+thur+fri)/4=40
  122+fri=160 by 1
  fri=38

• avg=mon+tues+wed+thursdy/4=38
  since mon is given as 40
  40+tues+wed+thursdy=38*4
  t+w+thu=152-40=112
  from second equation i.e..,t+w+thu+f/4=40
  therefore 112+f=160
  f=160-112=48

• (monday + tuesday+wednesday+ thursday)/4=38
  the temperatures of them together are : monday+tuesday+wednesday+thursday=38*4=142
  given, tuesday+wednesday+thursday+friday/4=40=40*4=160
  monday temperature=30 , substituting this in the above equation
  tuesday+wdnesday+thursday=142-30=112
  fridays temperature=160-112=48

• mon+tue+wed+thur = 38 * 4 = 152, where mon = 30
  30+tue+wed+thur = 152,
  tue+wed+thur = 122
  tue+wed+thur+fri = 40*4
  tue+wed+thur+fri = 160
  122+fri=160
  fri=38
