Find The rate % based question
Shortcut tricks on rate % based are one of the most important topics in exams. Competitive exams are all about time. If you manage your time then you can do well in those exams. Most of us skip that part. Few examples on rate % based shortcuts is given in this page below. All tricks on rate % based are provided here. We request all visitors to read all examples carefully. These examples will help you to understand shortcut tricks on rate % based.
Before doing anything we recommend you to do a math practice set. Then find out twenty math problems related to this topic and write those on a paper. Solve first ten math problems according to basic math formula. You also need to keep track of timing. Write down the time taken by you to solve those questions. Now read our examples on rate % based shortcut tricks and practice few questions. After doing this go back to the remaining ten questions and solve those using shortcut methods. Again keep track of the time. The timing will be surely improved this time. But this is not all you want. If you need to improve your timing more then you need to practice more.
Math section in a competitive exam is the most important part of the exam. It doesn’t mean that other topics are not so important. But only math portion can leads you to a good score. You can get good score only by practicing more and more. The only thing you need to do is to do your math problems correctly and within time, and you can do this only by using shortcut tricks. But it doesn’t mean that you can’t do math problems without using any shortcut tricks. You may have that potential that you may do maths within time without using any shortcut tricks. But other peoples may not do the same. Here we prepared rate % based shortcut tricks for those people. Here in this page we try to put all types of shortcut tricks on rate % based. But it possible we miss any. We appreciate if you share that with us. Your help will help others.
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. 40,000/- is 1/5 of the principle. Find the rate of interest of simple interest p.c.p.a.
Answer :40,000 x 1 / 5 = 8000
SI = PRT / 100 =
R = 40,000 x 5 / 100 x 8000 = 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, and then he received Rs. 2200 as a interest from of 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%
At what rate percent annul will a sum of money double in a 4 years.
Let Principle is = P.Then S.I = P and Time = 4 years.
S.I. = ( PRT/100 ).
So, R = ( 100X P / P X T ) %.
R = 25%
What is the rate of p.c.p.a ? If the simple interest accrued on amount of Rs.25500 at the end of 3 years is 9180.
we know the formula is S.I = PRT / 100
So, S.I = 9180 , P = 25500 , T = 3 years , R = ?
9180 = 25500 x R x 3 / 100
R = 9180 / 765 = 12 %
So rate of p.c.p.a = 12 %
A sum of money is in double in 12 years At what rate percent per annul.
Let Principle = P. Then S.I = P and T is given 12 years.
Rate = ( 100 X P / P X 12 ) = 8.33%
So R = 8.33 %
If the Simple interest accrued in 8 years on a principal of Rs.40,000/- is 8000 of the principal. What is the rate of simple interest p.c.p.a?
SI = PRT / 100
Let the rate of simple interest is x
So, x = 100 x 8000 / 40000 x 8
x = 2.5
So the rate of simple 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 p.c.p.a ?
Answer: We know the formula S.I = PRT / 100
9504 = 26400 x r x 3 / 100
r = 9504 / 264 x 3 = 9504 / 792 = 12%
