Assume temperatures of June, July,August, September be a, b, c, d.
From the data
(a+b+c)/3 =31
》》》 a+b+c=93.--------(1)
(b+c+d)/3 = 30
》》》 b+c+d=90.-------(2)
We also have temp of June to be 29. I.e a=29.
Therefore, Substituting in first eqn.
We get b+c =93-29 =64.
Now substituting b+c =64 in second eqn , we get
64+d=90
》》》 d=26
Therefore, temperature of September is 26.
