Question

Find the principal when simple interest for 10 years at 6.25 percentage is Rs 250.

Answer 1

Answer:

400

Step-by-step explanation:

simple interest = principal*time*rate/100

250 = principal * 10 * 6.25

principal = 250*100/6.25*10

principal = 400

Answer 2

Answer:

The principal amount is 400 rupees.

Step-by-step explanation:

The simple interest on an amount $P$ for $N$ years at a rate of $R$ percentage per year determined using the formula,

$I=\dfrac{PNR}{100}$

Given that the interest on a certain amount for 10 years at 6.25 percentage is 250 rupees. Thus we have

$250=\dfrac{P\times 10\times 6.25}{100}= 0.625P\\\\\implies P=\dfrac{250}{0.625}= 400$

So the principal amount is 400 rupees.
