Mean temperature of Monday to Wednesday = 37
Total temperature of Monday to Wednesday= 37 * 3 = 111
Mean temperature of Tuesday to Thursday = 34
Total temperature of Tuesday to Thursday = 34 * 3 = 102
Monday to Wednesday - Tuesday to Thursday = 111 - 102 = 9
Above statement we get
Monday - Thursday = 9
Let Monday = 5x
Thursday = 4/5 * Monday
= 4/5 * 5x
= 4x
Monday - Thursday = 9
5x - 4x = 9
x = 9
Thursday temperature = 4x = 4 * 9 = 36
