The simple interest on a certain sum P i...

The simple interest on a certain sum P is I and the amount is A. The rate of interest is R. Write the equations for P,R,T and A. `I=(PTR)/(100).`

Text Solution

Verified by Experts

`I=(PTR)/(100)`
`A=P+I`
`P=(100I)/(TR)`
`R=(100I)/(PT)`
`T=(100I)/(PR`
`A=P+I=P+(PTR)/(100)=P"("1+(TR)/(100)")"`
