[tex] \bf \underline{Given :}[/tex]
[tex] \sf{• \: Principal \: (P) = \$ \: 2000}
[/tex]
[tex] \sf{• \: Simple \: Interest \: (I) = \$ \: 1000}
[/tex]
[tex] \sf{• \: Time \: (T) = 10 \: years}[/tex]
[tex] \sf{• \: Interest \: Rate \: (R) = \: ?}[/tex]
[tex] \bf \underline{Solution:-}[/tex]
[tex] \sf {We \: know \: that, }[/tex]
[tex]\bf \red{\bigstar{ \: I = PRT}}[/tex]
[tex] \sf{⟹1000 = 2000 \times \frac{R}{100} \times 10 }[/tex]
[tex] \sf{⟹1000 = \frac{R}{100} \times 20000}[/tex]
[tex] \sf{⟹ \frac{R}{100} = \frac{1000}{20000} }[/tex]
[tex] \sf{⟹R = \frac{1}{20} \times 100 }[/tex]
[tex] \sf⟹ R = 5[/tex]
[tex] \pink{\bf{Hence, \: the \: interest \: rate \: is \: 5 \: \%. }}[/tex]
