The correct option is D 29∘
mean temperature of the week =25∘C
∴ Sum of the temperatures of 7 days = 7×25∘C=175∘C Sum of temperatures on Monday , Tuesday,Wednesday,And Thursday=4×23∘C=92∘C
Sum of temperatures on Thursday, Friday, Saturday, and Sunday=4×28∘C=112∘C
Sum of temperatures from Monday to sunday and Thursday = 92∘C+112∘C=204∘C Temperature on thursday=204∘C−175∘=29∘C
