If the simple interest on sum of money is 1/3 of the sum in 3 yrs find

1.	If the simple interest on sum of money is 1/3 of the sum in 3 yrs find the rate of interest
Answer» Step-by-step explanation: TIME = 3 years SI = 1/3 of the sum To find: The rate of INTEREST. Solution: The SIMPLE interest on any principal is given by: SI = \frac{PRT}{100}SI= 100 PRT So in the QUESTION SI = P/3 Put it in the formula, \frac{P}{3} = \frac{PR.3}{100} 3 P = 100 PR.3 \frac{1}{3} = \frac{R.3}{100} 3 1 = 100 R.3 \frac{100}{9} = R 9 100 =R R = 11\frac{1}{9}%R=11 9 1 % So the rate of the interest will be R = 11\frac{1}{9}%R=11 9 1 %.

If the simple interest on sum of money is 1/3 of the sum in 3 yrs find the rate of interest

Answer»

Step-by-step explanation:

TIME = 3 years

SI = 1/3 of the sum

To find:

The rate of INTEREST.

Solution:

The SIMPLE interest on any principal is given by:

SI = \frac{PRT}{100}SI=

100

PRT

So in the QUESTION SI = P/3

Put it in the formula,

\frac{P}{3} = \frac{PR.3}{100}

100

PR.3

\frac{1}{3} = \frac{R.3}{100}

100

R.3

\frac{100}{9} = R

100

R = 11\frac{1}{9}%R=11

So the rate of the interest will be R = 11\frac{1}{9}%R=11
