Answer 2

Principal Now=₹3600
Rate=4%
LET time=x years

It will Amount=₹4320
SI=amount-principal
SI=₹4320-3600
SI=₹720

$si = \frac{principal \times rate \times time}{100} \\ \frac{3600 \times 4 \times x}{100} = 720 \\ 144x = 720 \\ x = 720 \div 144 \\ x = 5 \\ \\ time = 5 \: years \\ \\ any \: doubt \: ask \\ thanks$
