Hello Friends, In this article we are going to share some most important short tricks of compound interest problems in Hindi as well as English language. This post also contain some definitions, short tricks types and important questions. This is very useful for those students who want to crack various entrance examinations.

## Type and Compound Interest Short tricks 1:- compound interest formula

#### r = {(D/P)^(1/2)} x 100%

Example:- At how much rate per annul interest of 1600 rs in 2 years, the compound interest become 164 rs ?\

Type and Compound Interest Short trick 2:- compound interest formula

1. Any wealth given on compound interest becomes m times in t years, then time for becoming m^n=(t x n) years.
2. Any wealth given on compound interest becomes m times in t years, then in (t x n) years that wealth become m^n of it.

Example:-Any wealth given on compound interest becomes twice in 5 years, then in how much years that wealth will becomes its 8 times?

## Type and Compound Interest Short tricks 3:- compound interest formula

#### 4 If simple interest of any wealth of second years is X rs and compound interest of second years is Y rs, then that wealth will be :- P = {(X^2) /  (Y-X)} rs

Example:-On any wealth at fixed rate, simple interest of 2 years is 800 rs and compound interest is 820 rs , then what will be the rate of interest per annul?

## Type and Compound Interest Short tricks 4:- interest formula compound

If any wealth at fixed rate of compound interest in t years become X rs and in 2t years become Y rs , then that wealth = {(X^2) / Y }rs

Example:-If any wealth at fixed rate of compound interest in 3 years become 4500 rs and in 6 years become 13500 rs , then find that wealth?

## Type and Compound Interest Short trick 5:- si and ci formula

#### If on any wealth the simple interest is X rs and on same wealth at any rate in any time compound interest is Y rs , then:- 1 Y = X {1 + (r/200)} 2 X = Y / {1 + (r/200)}

Example:- On any wealth at the rate is 10% per annul in 2 years simple interest is 4000 rs. On same  wealth at any rate in any time how much will be compound interest?

## Type and Compound Interest Short trick 6: – compound interest formula with example

#### If any wealth at rate r% of simple interest in 2 years become X rs and same wealth on compound interest at any rate in any time becomes Y rs, then:- 1 Y = X x [1+ {(r/10)^2} / (100 + 2r)] 2 X = Y / [1+ {(r/10)^2} / (100 + 2r)]

Example:- If any wealth at rate 10% of simple interest in 2 years become 2400 rs , then same wealth on compound interest at any rate in any time will become how much?

## Type and Compound Interest Short trick 7: – compound interest formula with example

#### If amount of X rs at the rate r% of compound interest in 2 years become Y rs , then:- 1 Y = [X x {100 + 2r + (r^2 / 100)}] / 100 2 X = (Y x 100) / {100 + 2r + (r^2 /100)}

Example:- How much will be the Amount of 5000 rs at the rate of 5% per annul compound interest in 2 years?

## Type and Compound Interest Short trick 8:- si and ci formula

1. On any sum ‘P’ in 2 years at the rate of r% per annul, the difference between compond interest and simple interest is = (Pr^2) / (100^2)
2. On any sum ‘P’ in 3 years at the rate of r% per annul, the difference between compond interest and simple interest is = Pr^2(300+r) / (100^3)

Example:- What will be difference between compound interest and simple interest on 50000 rs at the rate 4% per annul in 3 years?

## Type and Compound Interest Short trick 9:- si and ci formula

#### If compound interest of any wealth of second year is X rs then that wealth will be:-                                       ‘P’ = X x 100 / {1 + (r/100)}   Example:- What will be the principle of which compound interest of second year is 660 rs at the rate of 10% per annul?

Example:-If any credit of 441 rs is paid in two yearly installments. If rate of compound interest is 5% , how much wealth has credit?

## Type and Compound Interest Short trick 11: – compound interest formula with example

#### If compound interest of X rs at the rate of r% in two years is Y rs , then:- 1 Y = [X x {2r + (r^2/100)}] / 100 rs 2 X = Y x 100 / {2r + (r^2/100) rs Example:- what will be the compound interest on 1000 rs at the rate of 8% per annul compound interest in 2 years

Example:- What will be the compound interest of 16000 rs at the rate of 1x(1/2) per year , wheres as the interest will charged per monthly ?
