The mean temperature of Monday to Wednesday was 37°C and of and of Tuesday to Thursday was 34°C. If the temperature on Thursday was $$\frac{4}{5}$$ that of Monday, the temperature of Thursday was-

A. 34°C

B. 35.5°C

C. 36°C

D. 36.5°C

Answer: Option C

Solution(By Examveda 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
