The average temperature from Mon to Wed is 37°C while the average temperature from Tue to Thu is 34°C. The temperature of Thurs is \(\frac{4 }{5}\) times that of Mon. Find the temperature of Thursday.

32°C

\(\frac{Mon + Tue + Wed}{3}\) = 37

Mon + Tue + Wed = 37 × 3 = 111    ------(i)

\(\frac{Tue + Wed + Thu}{3}\) = 34

Tue + Wed + Thur = 34 × 3 = 102    ------(ii)

Subtract eqn (ii) from (i), we get

Mon - Thu = 9 ---------- (iii)

ATQ,

       Thu = \(\frac{4}{5}\) Mon (Put this value in eqn (iii))

       Mon - \(\frac{4}{5}\) Mon = 9

                                      Mon = 45

                Thu = 45 x \(\frac{4}{5}\) = 36° C
