Compound Interest is difference between the original principal and final amount is called Compound Interest ( CI ). Compound Interest is Similar to Simple Interest shortcut tricks as we know that same for some time but some cases its different from Simple Interest, In case of Compound Interest the interest is vary according to time but the first year it is equal always that is.

1st year Interest is “**Compound Interest = Simple Interest”**. But **after that year it is increases. 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 .**

When we use this given below formulas some calculation it takes too much time and when we try to solve it, it become lengthy, So reduces the taking time to solve problems we give some extra shortcut tricks which helps you for fast calculation.

**Some important formula of Compound Interest**

- A = Amount.

P = Principal.

R = Rate of Interest.

N = Number of Years.

**Type I : Interest compounded yearly :**

**A = P ( 1 + r / 100 )**^{n}

**Type II : Interest compounded half – yearly :**

Amount =**P [ 1 + r / 2 / 100 ]**or = P =^{2n}**[ 1 + r / 200 ]**^{2n}

**Type III : Interest compounded quarterly :**

Amount =**P [ 1 + r / 4 / 100 ]**or =**P [ 1 + r / 400 ]**^{4n}

In Compound Interest problems asked in exams up to the period of 3 years.

In case we apply basic formula: Amount =Principal ( 1 + r / 100 )^{n} here r = Rate and n = Time

As consider if Principal is Rs. 1, then the it will be in first year and second and third years.

( 1 + r / 100 )^{1}

( 1 + r / 100 )^{2}

( 1 + r / 100 )^{3}

If the rate of interest is 5%, then the value will be …….

In first year = (21 / 20 ) = 21 / 20.

In second year = ( 21 / 20 )^{2} = 441 / 400.

In Third year = ( 21 / 20 )^{3} = 9261 / 8000.

Very good website with a lot of helpful maths tricks ,thanks to all those who devoloped this website.

How is it 23/21 for 3 %

super

Thank you sooooooo much fo giving this shatcut method

how you find that 23/21?

If rate of interest is 5% then first year it will be 105 / 100 = 21 / 20

If rate of interest is 5% then second year it will be (105 / 100)^2 = 441 / 400

If rate of interest is 5% then 3rd year it will be (105 / 100)^3 = 9261 / 8000

Good and helpfull
