Which of the following shows the maximum rise in temperature
a. 23° to 32°
b. -10° to + 1°
c. -18° to -11°
d. -5° to 5°
Solution:
If we carefully observe the individual options we note that
The difference in the temperature = 1° -(-10°) = 11° (this is a maximum)
23° to 32° = 32°- 23°= 9°
-18° to -11° = -11° - (-18)°= 7°
-5° to 5° = 5°- (-5)°= 10°
Therefore the option (b) -10° to + 1° shows the maximum rise in the temperature.
✦ Try This: Which of the following will give greater value of integer -23 + 25 or -25 + 23.
Using the integer rules and the BODMAS rules we can determine the value of -23 + 25 or -25 + 23. Thus can examine which will give the greater integer value
