Here is complete explanation of The mean temperature of Monday to Wednesday was 37 C and….

Solution(By ExamCraze Team)

M + T + W = (37 × 3)°C = 111°C.....(i)
T + W + Th = (34 × 3)°C = 102°C.....(ii)
Subtracting (ii) from (i), we get:
⇒ M - Th = 9°C
⇒ M - $$frac{4}{5}$$M = 9
⇒ $$frac{1}{5}$$ M = 9
⇒ M = 45
∴ Temperature on Thursday
= $$left( {frac{{4}}{{5}}} times 45 right)$$ °C
= 36°C
