Amount of Interest=7152-6400=752=I
- Principal=6400=P
- Rate of interest=6%=R
- Time=T=?
We know
[tex]\boxed{\sf I=\dfrac{PRT}{100}}[/tex]
[tex]\\ \sf\longmapsto T=\dfrac{PR}{100I}[/tex]
[tex]\\ \sf\longmapsto T=\dfrac{6400(6)}{100(752)}[/tex]
[tex]\\ \sf\longmapsto T=\dfrac{38400}{75200}[/tex]
[tex]\\ \sf\longmapsto T\approx 0.5year[/tex]
[tex]\\ \sf\longmapsto T\approx 6months[/tex]
