(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
