The simple interest obtained in 5 years on a principal of Rs.40000/- is 1/5 of the principle. Find the rate of interest of simple interest per annum.
SI = 40000 x 1 / 5 = 8000
SI = P x T x R / 100
SI = 40000 x 5 x R / 100
R = 40000 x 5 / 100 x 8000 = 4%
So, the rate of interest is 4%.
Amit give Rs.6000/- to Bijoy for 2 years and Rs.2000/- to Sabir for 5 years on simple interest at same rate of interest. He received Rs.2200/- as an interest from them. Find the rate of interest per annum.
We know formula SI = P x R x T / 100
So, R% = ( 6000 x R x 2 / 100 ) + ( 2000 x R x 5 / 100 ) = 2200
R% = 120R + 100R = 2200
R = 2200 / 220 = 10%
So, the rate of interest is 10%.
At what rate percent per annum, a sum of money double in a 4 years.
Let, Principle is = P
Then SI = P and
Time = 4 years
So, R = ( 100 X P / P X 4 ) %
R = 25%
So, the rate of interest is 25%.
What is the rate of percent per annum if the simple interest accrued on amount of Rs.25500/- at the end of 3 years is Rs.9180/- ?
SI = 9180
P = 25500
T = 3
R = ?
So, 9180 = 25500 x R x 3 / 100
R = 9180 / 765 = 12%
So, the rate of interest is 12%.
A sum of money is doubled in 12 years. Find the rate of percent per annum.
Let, Principle = P
Then, SI = P and
T = 12
R = ( 100 x P / P x 12 ) = 8.33%
So, the rate of interest is 8.33%.
If the simple interest accrued in 8 years on a principal of Rs.40000/- is Rs.8000/- of the principal. What is the rate of simple interest per annum?
So, R = 100 x 8000 / 40000 x 8
R = 2.5%
So, the rate of interest is 2.5%.
The simple interest deposited on an amount of Rs.26400/- at the end of 3 years is Rs.9504/-. What would be the rate of interest per annum?
So, 9504 = 26400 x R x 3 / 100
R = 9504 / 264 x 3 = 9504 / 792 = 12%
So, the rate of interest is 12%.
