Answer 1

$$\begin{gathered} \mathrm{The}\mathrm{initial}\mathrm{amount}\mathrm{in}\mathrm{the}\mathrm{bank}\mathrm{account}\mathrm{is}\mathrm{Rs}20,000 \\ \mathrm{It}\mathrm{is}\mathrm{given}\mathrm{that}\mathrm{the}\mathrm{person}\mathrm{withdraws}\mathrm{Rs}3000\mathrm{each}\mathrm{for}\mathrm{the}\mathrm{next}\mathrm{three}\mathrm{months}. \\ \mathrm{Thus}\mathrm{the}\mathrm{amount}\mathrm{withdrawn}\mathrm{in}\mathrm{first}\mathrm{month}\mathrm{is}\mathrm{Rs}3000,\mathrm{amount}\mathrm{withdrawn}\mathrm{in}\mathrm{second} \\ \mathrm{month}\mathrm{is}\mathrm{RS}3000,\mathrm{in}\mathrm{third}\mathrm{month}\mathrm{the}\mathrm{amount}\mathrm{withdrawn}\mathrm{is}\mathrm{again}\mathrm{Rs}3000. \\ \mathrm{The}\mathrm{total}\mathrm{amount}\mathrm{withdrawn}\mathrm{in}\mathrm{three}\mathrm{months}\mathrm{will}\mathrm{be}, \\ \mathrm{Rs}3000+\mathrm{Rs}3000+\mathrm{Rs}3000=\mathrm{Rs}9000 \\ \mathrm{The}\mathrm{balance}\mathrm{in}\mathrm{the}\mathrm{acoount}\mathrm{can}\mathrm{be}\mathrm{found}\mathrm{by}\mathrm{subtracting}\mathrm{this}\mathrm{amount}\mathrm{from}\mathrm{the}\mathrm{initial} \\ \mathrm{amount}. \\ \mathrm{Rs}20,000-\mathrm{Rs}9000=\mathrm{RS}11,000 \\ \mathrm{Thus}\mathrm{the}\mathrm{remaining}\mathbf{balance}\mathbf{}\mathbf{in}\mathbf{}\mathbf{the}\mathbf{}\mathbf{bank}\mathbf{}\mathbf{account}\mathbf{}\mathbf{}\mathbf{is}\mathbf{}\mathbf{Rs}\mathbf{}\mathbf{11}\mathbf{,}\mathbf{000} \end{gathered}$$
