Answer 2

Given :

The sum of money that will produce Rs 1770 as simple interest in 7 1/2 years as 8% at per annum

To Find :

Find the sum

Solution:

Let the sum be x

Simple interest = Rs.1770

Time =$7 \frac{1}{2}=\frac{15}{2} years$

Rate of interest = 8%

Formula :

$SI = \frac{P \times T \times R}{100}$

$1770=\frac{x \times 15 \times 8}{2 \times 100}$

$\frac{1770 \times 100 \times 2}{15 \times 8}=x$

2950 =x

Hence The sum of money is Rs.2950
