1. Find Present value C = ?
Interest Rate i = 10%, Time n = 3 Year, Future value FV = 1300,
for Future value using Simple Interest method

Solution:
`i=10%=0.1` per year (Interest rate)

`n=3` years (Number of periods)

`FV=1300` (Future value)

Now, Future value (Simple Interest) formula is
`FV=C*(1+i*n)`

`:.1300=C*(1+0.1*3)`

`:.1300=C*(1+0.3)`

`:.1300=C*(1.3)`

`:.C=(1300)/(1.3)`

`:.C=1000`

2. Find Present value C = ?
Interest Rate i = 10%, Time n = 2 Year, Future value FV = 6000,
for Future value using Simple Interest method

Solution:
`i=10%=0.1` per year (Interest rate)

`n=2` years (Number of periods)

`FV=6000` (Future value)

Now, Future value (Simple Interest) formula is
`FV=C*(1+i*n)`

`:.6000=C*(1+0.1*2)`

`:.6000=C*(1+0.2)`

`:.6000=C*(1.2)`

`:.C=(6000)/(1.2)`

`:.C=5000`
