45 m above sea level = +45
25 m below sea level = -25
Therefore, 45 - (-25) = 70
25 m below sea level = -25
Therefore, 45 - (-25) = 70

A place is 45 metre above sea level and another place is 25 meter belo...
Given:
- The first place is 45 meters above sea level.
- The second place is 25 meters below sea level.
To find: The difference of level in meters between the two places.
Solution:
- We need to find the total difference in level between the two places, which can be calculated by adding the difference in their heights.
- The height of the first place is 45 meters above sea level, so we can write it as +45 meters.
- The height of the second place is 25 meters below sea level, so we can write it as -25 meters.
- To find the difference in level, we need to subtract the height of the second place from the height of the first place.
- The calculation would be: Difference in level = Height of first place - Height of second place
- Substituting the values, we get: Difference in level = (+45 meters) - (-25 meters) = +45 + 25 = 70 meters.
- Therefore, the difference in level between the two places is 70 meters.
Answer: The correct option is (c) 70.
- The first place is 45 meters above sea level.
- The second place is 25 meters below sea level.
