Answer 2

$\green{ \boxed{ \boxed{39° \: C}}}$

$\purple{ \underline{ \mathfrak{solution}}}$

>>Average temperature for Wednesday, Thursday and Friday =40°C

Total temperature =3×40°C=120°C

>>Average temperature for Thursday, Friday and Saturday =41°C

Total temperature =41°C×3= 123°C

Temperature on Saturday = 42°C

Now,

>>(Thursday+Friday+Saturday)−(Wednesday+Thursday+Friday)=123°C - 120°C

Saturday−Wednesday=3

Hence, Wednesday= 42°C - 3 = 39°C
