# Represent the following numbers as integers with appropriate signs.(a) An aeroplane is flying at a height two thousand metre above the ground.(b) A submarine is moving at a depth, eight hundred metre below the sealevel.(c) A deposit of rupees two hundred.(d) Withdrawal of rupees seven hundred

To do:

We have to represent the given numbers as integers with appropriate signs.

Solution:

(a) We take the ground level(sea level) as zero and everything above it as positive.

Therefore,

The given number as integer with appropriate sign is $+2000\ m$.

(b) We take the sea level as zero and everything below it as negative.

Therefore,

The given number as integer with appropriate sign is $-800\ m$.

(c) ‘A deposit of rupees two hundred'  $= +200₹$

The sign should be $+$ because we are depositing it in our bank account.

$+200₹$ is an integer representation of the sentence ‘A deposit of rupees two hundred.'

(d) Withdrawal of rupees seven hundred $= -700₹$

The sign should be $-$ because we are withdrawing it from our bank account.

$-700₹$ is an integer representation of the sentence 'Withdrawal of rupees seven hundred'.
