Question

Mohan deposits \(₹\,2000\) 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?

Text Solution

What is known?

The amount deposited and the amount withdrawal.

What is the unknown?

Balance after the withdrawal.

Reasoning:

To find the balance you have to subtract the amount deposited and the amount withdrawal.

Steps:

Amount deposited by Mohan \(= ₹\, 2000\) (amount deposited can be represented by a positive integer)

Amount withdrawn by Mohan \(= ₹\,1642\) (amount deposited can be represented by negative integer)

Balance in Mohan’s account \(=\) amount deposited – amount withdrawal

\[\begin{align}\\&= ₹ (2000–1642)\\&= ₹\,358\end{align}\]

Hence,the balance in Mohan’s account after withdrawal is \(₹\,358.\)
