Question

The temperature of a place falls by 7°C, then rises by 15°C and again falls by
9°C. What will be the final temperature, if the initial temperature was 28°C?

Answer 1

Initial Temperature = 28°C

Temp. changes = –7° + 15° –9° = –1°

Therefore, there is a total change of –1°C.

Final Temperature = 28° – 1° = 27°C
