As part of a geography assignment, Suresh recorded the temperature of his city at different times of the day. The temperature was \(37.4^{\circ}C\) in the afternoon and \(31.2^{\circ}C\) at the night. He used decimal numbers to note small variations in temperature accurately. This helped him analyse the change in temperature from afternoon to night.
Based on the given information solve the following questions
1. What was the decrease in temperature from afternoon to night?
2. If the temperature at night was recorded with one decimal place less accuracy as \(31^{\circ}C\), how much information is lost?
3. If the temperature drops by another \(0.5^{\circ}C\) at night, what will be the new temperature?
4. Which of the folowing decimal numbers lies between the afternoon and night temperatures recorded by Suresh?
