Given:

Amount = 60000

Interest rate = 4% per yaer

Find: she have in 9 months.

Sol:.

In 12 month 4% interest rate then amount is:

`\begin{gathered} In\text{ 12 month value =}(104)/(100)*60000 \\ =62400 \end{gathered}`

In 12 month amount is 62400

`\begin{gathered} =62400-60000 \\ =2400 \end{gathered}`

In 12 mounth amount increasses is 2400

so in 9 month:

`\begin{gathered} =(2400)/(12)*9 \\ =1800 \end{gathered}`

After 9 month amount is:

`\begin{gathered} \text{Amount}=60000+1800 \\ =61800 \end{gathered}`
