Work Step by Step

The provided formula is\[I=P.r.t\] and now solve the formula for \[P\]by dividing both the sides by \[rt\]. \[\begin{align} & I=P.r.t \\ & \frac{I}{rt}=\frac{P..}{} \\ & P=\frac{I}{rt} \end{align}\] The formula \[I=P.r.t\]is for simple interest, where \[I=\]interest earned on principal value, \[P=\]principal value, \[r=\]rate at which the interest is earned, and\[t=\]the time duration in which the interest is earned. The formula is\[P=\frac{I}{rt}\].
