Let temperature on monday be x1
tuesday be x2
wednesday be x3
thursday be x4
then (x1+x2+x3)/3 = 37
and (x2+x3+x4)/3 = 34
given x4 = (4/5)x1
Using three equations we get the value of x1 as 45
so temperatue on thursday is (4/5)x1 = (4/5)45 = 36Deg

The total sum of temp on
Monday+Tuesday+Wednesday=(37*3)=111---------equation 1

and that of

Tuesday+Wednesday+Thursday=34*3=102---------equation 2

subtracting equation 2 from equation 1 ,We get

Monday-Thursday=111-102=9-------------equation 3

But Thursday=4/5 Monday------------------equation 4

Substituting equation 4 in equation 3,
We get (1/5*Monday)=9

Temp on Monday=9*5=45

Temp on Thursday=4/5*Temp on Monday=(4/5)*45 =36 degree centigrade

Given avg temp on Mon, tue and wed is 37
i.e. (M+Tu+W)/3=37

=> M+Tu+W=37*3=111------(1)

avg temp on Tue, Wed, Thu is 34

=> (Tu+W+Th)/3=34
=> Tu+W+Th=34*3=102----------(2)

Subtract (2) from (1)

we get M-Th=111-102=9

Given Th=(4/5)*M

Now it says, Mean temperature of first three days = 37 °C
so (5x+2y)/3=37
And Mean Temperature for last three days is 34 °C
so (4x+2y)/3=34

solving both equations we get x=9
