If we consider the level of the sea at neutral level,

Then the height above the sea level is considered as positive

And,

The height below the sea level is considered as negative.

Hence,

According to the question,

The integer with appropriate sign will be +2000.

(b) In the given question,

If we consider the level of the sea at neutral level,

Then the height above the sea level is considered as positive

And,

The height below the sea level is considered as negative.

Hence,

According to the question,

The integer with appropriate sign will be -800.

(c) We know that,

Deposit refers to the saving of money
