Question

Mohan deposits ₹2,000 in his bank account and withdraws ₹1,642 from it, the next day. If withdrawal of amount from the account is represented by a negative integer, then how will you represent the amount deposited? Find the balance in Mohan’s account after the withdrawal.

Answer 1

Since the amount withdrawn is represented by a negative integer, the amount deposited will be represented by a positive integer.
Amount deposited = + ₹2,000
Amount withdrawn = − ₹1,642
Balance in Mohan’s account = Money deposited + Money withdrawn
= ₹2,000 + (−₹1,642) = ₹(2,000 − 1,642) = ₹358
Therefore, balance in Mohan’s account after withdrawal is ₹ 358.
