Given:

Mohan deposits $Rs.\ 2,000$ in his bank account and withdraws $Rs.\ 1,642$ from it, the next day.

The withdrawal of the amount from the account is represented by a negative integer.

To do:

We have to find how we represent the amount deposited and the balance in Mohan’s account after the withdrawal.

Solution:

The amount deposited in the bank account $= Rs.\ 2000$

The amount withdrawn from the bank account $= Rs.\ 1642$

The withdrawal of the amount from the account is represented by a negative integer.

This implies,

The amount deposited will be denoted with a positive sign.

Therefore,

Balance in the account $=$ Amount deposited in bank account $+$ Amount withdrawn from the bank account

$= 2000 + (-1642)$

$= 2000 - 1642$

$= 358$

Therefore, the balance in Mohan’s account after the withdrawal is $Rs.\ 358$.
