In what time will Rs. 6400 amount to Rs. 7152 at the rate of 6% p.a?​

Sagot :

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]
