The mean temperature of Monday to Wednesday was 37° C and of Tuesday to Thursday was 34° C . If in the temperature on Thursday was 4/5th that of Monday, what was temperature on Thursday ?
-
- 34° C
- 35.5° C
- 36° C
- 36.5° C
Correct Option: C
M + T + W = 3 x 37 = 111° C .....(1)
T + W + Th = 3 x 34 = 102 ° C ......(ii)
Let M = y
Then, Th = 4y/5
subtraction (ii) from (i) we get,
M - Th = 9° C
⇒ y - 4y / 5 = 9° C
⇒ y = 45° C
∴ Temperature on thursday = (4 x 45) / 5° C
= 36° C
