When we borrowed money from some one or we lent out some money for a some certain period is called the Principal or Sum. So here we, Find the Rate % based questions are given in bank exams and Time will be given. just using formula u get rate percent. This type of problem are given in Quantitative Aptitude which is a very essential paper in banking exam.Under below  given some more example for your better practice.

 

 

Example #1
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.

Answer
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%.

 

Example #2
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.

Answer
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%.

 

Example #3
At what rate percent per annum, a sum of money double in a 4 years.

Answer
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%.

 

Example #4
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/- ?

Answer
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%.

 

Example #5
A sum of money is doubled in 12 years. Find the rate of percent per annum.

Answer
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%.

 

Example #6
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?

Answer

So, R = 100 x 8000 / 40000 x 8
R = 2.5%

So, the rate of interest is 2.5%.

 

Example #7
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?

Answer
So, 9504 = 26400 x R x 3 / 100
R = 9504 / 264 x 3 = 9504 / 792 = 12%

So, the rate of interest is 12%.
