One rupee interest on hundred rupees means how much percentage?

If you receive one rupee as interest on a hundred rupees, you can calculate the percentage interest by dividing the interest amount by the principal amount and then multiplying by 100.

In this case, the interest amount is one rupee, and the principal amount is one hundred rupees.

Percentage interest = (Interest amount / Principal amount) * 100

Percentage interest = (1 / 100) * 100

Percentage interest = 1%

Therefore, receiving one rupee as interest on a hundred rupees corresponds to a 1% interest rate.
