## 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Amount withdrawn by Mohan \(= ₹\,1642\) (amount deposited can be represented by negative integer)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 \(₹\,358.\)
