31 --------------------> 8

32 --------------------> 6

A. 29

B. 30

C. 30.5

D. 31

E. 32

P.S: Bunuel-Can you please explain this?

to find out median===>they must be arranged in ascending order.

29 29 29...(5 times)30 30 30 30.....(11 times)31 31 31.....(8 times)32 32 32 .....(6 times)

total days=5+11+8+6=30

therefore 30 numbers ...median will be==>mean of 15 and 16 th place temperature===>(30+30)/2=30

hence B

Hope it helps
