From 9.00 AM to 2.00 PM, the temperature rose at a constant rate from 21°C to 36°C. What was the temperature at noon ?
-
- 27°C
- 30°C
- 32°C
- 28.5°C
- 27°C
Correct Option: B
On the basis of above given question ,
Temperature difference in 5 hours = 36 – 21 = 15°C
∴ Temperature difference in 3 hours = 9°C
Hence, required temperature = 21 + 9 = 30°C
