Question

A sum of money put out at simple interest amounted to Rs. 915 in 4 years at 5.5% per annum. What is the sum​

Answer 1

Given,

• Simple Interest (I) = Rs 915

• Rate of interest (r) = 5.5

• Time (n) = 4 years

We know the equation:

$\boxed{\sf{Principle \ amount = \dfrac{I\times 100}{n\times r}}}$

$\sf{\implies Principle \ amount = \dfrac{915\times 100}{4\times 5.5}}$

$\sf{\implies Principle \ amount = \dfrac{91500}{22}}$

$\sf{\implies Principle \ amount =Rs \ 4159.09}$

$\boxed{\sf{\therefore Principle \ amount =Rs \ 4159.09}}$
