Question

At what rate percent per annum the s.i on rs 12500 in 4/3/4 years is rs 2375.

Answer 1

Hi ,

It is given that ,

Principal ( P ) = Rs 12500 ,

Time ( T ) = 4 3/4 = 19/4 years

Simple interest ( I ) = Rs 2375

Let the rate of interest = R

***********************************

We know that ,

S.I = ( PTR )/100

or

R = ( 100 × I )/PT

***************************************

R = ( 100 × 2375 )/( 12500 × 19/4 )

R = ( 100 × 2375 × 4 )/( 12500 × 19 )

R = ( 2375 × 4 )/( 125 × 19 )

R = ( 19 × 4 )/19

R = 4

Therefore ,

Required rate of interest = R = 4%

I hope this helps you.
