(M+Tu+We+Th+Fr+Sat+Sun)/7=25
=>(M+Tu+We+Th+Fr+Sat+Sun)=175 -----(1)
(M+Tu+We+Th)/4=23
=>(M+Tu+We+Th)=92 -----------------(2)
(Th+Fr+Sat+Sun)/4=28
=>(Th+Fr+Sat+Sun)=112 -------------(3)
Substitute (2)in (1)
=>(Fr+Sat+Sun)=83 -----------------(4)
Now (3)-(4) gives temperature on thursday = 112-83=29c
