Question

If the interest on 6000 rupees is 400 rupees at a certain number of years, what would the interest be on 1500 rupees under the same conditions? *​

Answer 1

Answer:

Interest would be Rs.300.

Step-by-step explanation:

Since we have given that

Principal = Rs. 3000

Interest = Rs. 600

So, Simple interest formula would be

\begin{gathered}600=\dfrac{3000\times R\times T}{100}\\\\600\times 100=3000\times RT\\\\\dfrac{600\times 100}{3000}=RT\\\\20=RT\end{gathered}

600=

100

3000×R×T

600×100=3000×RT

3000

600×100

=RT

20=RT

If principal amount = Rs. 1500

Then, interest would be

Interest=

100

1500×20

Interest=Rs. 300
