Question

If the interest on 3000 rupees is 600 rupees at a certain rate for a certain number of years, what would the interest be on 1500 rupees under the same condition

Answer 1

Answer:

300 rupees.

Step-by-step explanation:

The simple interest formula is:

A = P * ( 1 + r t )

P is the principle amount of money and A is the interest.

600 = 3000 * ( 1 + r t )

x = 1500 * ( 1 +r t )

And under the same condition :

1 +  r t = 600 / 3000

x = 1500 * 600 / 3000 = 300.
