Question

Ruchi deposited $\mathrm{Rs}4380$ in her account on Monday and then withdrew $\mathrm{Rs}2885$ on Tuesday. Next day, she deposited $\mathrm{Rs}1560$. What was her balance on Thursday?

Answer 1

Amount deposited on Monday is represented as $=+\mathrm{Rs}4380$

Amount withdrawn on Tuesday is represented as $=-\mathrm{Rs}2885$

Amount deposited on Wednesday is represented as $=+\mathrm{Rs}1560$

Balance on Thursday$=\mathrm{Rs}4380+\left(-\mathrm{Rs}2885\right)+\mathrm{Rs}1560$

$$\begin{gathered} =\mathrm{Rs}(4380-2885+1560) \\ =\mathrm{Rs}3055 \end{gathered}$$

Hence, Ruchi's balance on Thursday $=\mathrm{Rs}3055$
