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Amount withdrawn by Mohan \(= ₹\,1642\) (amount deposited can be represented by negative integer)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