Question

find the amount Anita borrowed from a finance company if she paid RS.3600 as interest for 3 years at 3% interest per annum.

Answer 1

We know that:

• Interest = ₹ 3,600
• Time = 3 years
• Rate = 3%

Let "P" represent the money Anita borrowed.

`\frac{\text{P} * 3 * 3}{100} = 3,600`

`\rightarrow \frac{\text{P} * 9}{100} = 3,600`

`\rightarrow \frac{\text{P} }{100} = 400`

`\rightarrow \ \text{P }= \text{R.S} \ 40000`

Answer 2

Lets see

• Interest=I=3600
• Rate of interest=R=3%
• Time=T=3yrs

• Principle=P

`\\ \rm\longmapsto I=(PRT)/(100)`

`\\ \rm\longmapsto P=(100I)/(RT)`

`\\ \rm\longmapsto P=(360000)/(9)`

`\\ \rm\longmapsto P=Rs.40000`
