- An EMI (equated monthly installment) is a fixed monthly payment made towards a loan consisting of both principal and interest.
- The EMI can be calculated using the formula P = x/i(1-(1+i)^-n) where P is principal, x is monthly installment, i is monthly interest rate, and n is number of payments.
- Examples show calculating EMI for loans over different time periods (1-5 years) and interest rates (5-12% per year) by plugging values into the EMI formula.
There are a number of different methods of calculating investment return, depending on what you’re trying to measure. Perhaps the most basic is total return, which is simply an investment’s ending balance expressed as a percent of its beginning balance. Total return includes capital appreciation and income components; it assumes all income distributions are reinvested. To annualize total return, you’ll need to calculate the compound annual return, which generally requires using a financial calculator. It’s important to keep in mind that you need a greater percentage gain after a losing year in order to break even on your investment.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2. Simple Interest is an easy method of calculating the interest
for a loan/principal amount.
Simple interest is a concept which is used in most of the
sectors such as banking, finance, automobile, and so on.
Simple Interest (S.I) is the method of calculating the
interest amount for some principal amount of money.
3. Formula :-
SI = (P × R ×N) / 100
Where SI = simple interest
P = principal
R = interest rate (in percentage)
N = time duration (in years)
In order to calculate the total amount, the following formula is
used:
Amount (A) = Principal (P) + Interest (I)
Where,
Amount (A) is the total money paid back at the end of the time
period for which it was borrowed.
4. 1. Rishav takes a loan of Rs 10000 from a bank for a period of
1 year. The rate of interest is 10% per annum. Find the
interest and the amount he has to the pay at the end of a
year.
Solution :- Here, the loan sum = P = Rs 10000
Rate of interest per year = R = 10%
Time for which it is borrowed = N = 1 year
Thus, simple interest for a year,
SI = (P × R ×T) / 100
= (10000 × 10 ×1) / 100
= Rs 1000
Amount that Rishav has to pay to the bank at the end of the
year
= Principal + Interest
=10000 + 1000
= Rs 11,000
5. 2. Mohit pays Rs 9000 as an amount on the sum of Rs 7000 that
he had borrowed for 2 years. Find the rate of interest.
Solution:
Given A = Rs 9000
P = Rs 7000
SI = A – P = 9000 – 7000 = Rs 2000
T = 2 years
R = ?
SI = (P × R ×T) / 100
R = (SI × 100) /(P× T)
R = (2000 × 100 /7000 × 2) =14.29 %
Thus, R = 14.29%
6. 3 . Namita borrowed Rs 50,000 for 3 years at the rate of 3.5% per
annum. Find the interest accumulated at the end of 3 years.
Solution :- Given
P = Rs 50,000
R = 3.5%
T = 3 years
SI = (P × R ×T) / 100
= (50,000× 3.5 ×3) / 100
= Rs 5250
4. A sum of Money Doubles itself in 10 Years . Find the Rate of
Simple Interest .
7. When we observe our bank statements, we generally
notice that some interest amount is credited to our account
every year.
This interest varies with each year for the same principal
amount. We can see that interest increases for successive
years.
Hence, we can conclude that the interest charged by the
bank is not simple interest, this interest is known
as compound interest or CI.
8. Compound Interest Definition
Compound interest is the interest calculated on the
principal and the interest accumulated over the previous period.
It is different from the simple interest where interest is not
added to the principal while calculating the interest during the
next period.
Compound interest finds its usage in most of the
transactions in the banking and finance sectors and also in other
areas as well.
Some of its applications are:
Increase or decrease in population.
The growth of bacteria.
Rise or Depreciation in the value of an item.
10. Where,
A= amount
P= principal
R= rate of interest
n= number of times interest is compounded per
year
It is to be noted that the above formula is the general formula
for the number of times the principal is compounded in a year. If
the interest is compounded annually, the amount is given as:
A=P(1+R100)t
11. Examples 1:
A town had 10,000 residents in 2000. Its population declines
at a rate of 10% per annum. What will be its total population
in 2005?
Solution:
The population of the town decreases by 10% every year.
Thus, it has a new population every year. So the
population for the next year is calculated on the current
year population. For the decrease,
we have the formula
A = P(1 – R/100)n
Therefore, the population at the end of 5 years
= 10000(1 – 10/100)5
= 10000(1 – 0.1)5
= 10000 x 0.95
= 5904 (Approx.)
12. 2. The count of a certain breed of bacteria was found to
increase at the rate of 2% per hour. Find the bacteria at the end
of 2 hours if the count was initially 600000.
Solution:
Since the population of bacteria increases at the rate of
2% per hour, we use the formula
A = P(1 + R/100)n
Thus, the population at the end of 2 hours
= 600000(1 + 2/100)2
= 600000(1 + 0.02)2
= 600000(1.02)2
= 624240
13. A sum of Rs.10000 is borrowed by Akshit for 2 years at an interest
of 10% compounded annually. Calculate the compound interest and amount
he has to pay at the end of 2 years.
Solution:
Given,
Principal/ Sum = Rs. 10000,
Rate = 10%, and
Time = 2 years
From the table shown above it is easy to calculate the
amount and interest for the second year, which is given
by-
Amount(A) = P(1+R100)2
A2= =10000(1+10100)2
=10000(1110)(1110)
=Rs.12100
Compound Interest (for 2nd year)
= A2–P
= 12100 – 10000
= Rs. 2100
14. 1. Find The Compund Interset Rs.5000 at 4% p.a for 5 years .
2. Find C.I on Rs 5000 for 3 Yrs at 5% p.a . Compounded Yearly .

15. Introduction :-
We know that loans are made available by banks
and companies for the purchase of household items like
furniture , Tv Set items like flat etc .
An Annuity is a series of payments made at equal
intervals . They are equal or different When Payments are
equal , The annuity is called Simple Annuity .
16. Annuity due
Annuity due is an annuity whose payment is due
immediately at the beginning of each period.
Annuity due can be contrasted with an ordinary annuity
where payments are made at the end of each period.
A common example of an annuity due payment is rent paid
at the beginning of each month.
An example of an ordinary annuity includes loans, such as
mortgages.
The present and future value formulas for an annuity due differ
slightly from those for an ordinary annuity as they account for the
differences in when payments are made.
17. Immediate Payment Annuity
Immediate payment annuities are sold by insurance
companies and can provide income to the owner almost
immediately after purchase.
Buyers can choose monthly, quarterly, or annual
income.
Payments are generally fixed for the term of the
contract, but variable and inflation-adjusted annuities are
also available.
Relation Between Amount and Present Value
1/P - 1/a = i/x
18. Formula
Let P:- Present Value of immediate Annuity .
x: Periodic Installment
n:Number of Installments .
i: Rate of compound interest per rupee per
period
Then , P=x/i{ 1-(1+ i)-n
If A denotes the amount of immediate annuity then ,
A=x/i{(1+i)n-1 }
19. Example 1 Find the amount of an immediate annutiy of
rs 15000 12 years at 10% p.a .
Solution :- Here ,
x= Periodic installment
= 15000,
n= 12
i= 0.1
Amount of annuity A=x/i{(1+i)n-1 }
= 15000/0.1 { (1.1 )^12 -1}
= 15000 { 3.1384 -1 }
= 320764.26
20. 2. ULIP is a scheme of unit trust of india under which a person can
deposit upto Rs 10000/-Per year . The status of ULIP is 10 Years
or 15 years , A person takes a membership of ULIP by paying
10000 for 10 years . Assuming the rate of compound interst to be
12% . Find the amount he will receive at the end of 10 years .
Solution :- Here x = 10000
n = 10
i= 0.12
To find amount A
Now A=x/i [ (1 + I ) ^n -1 ]
= 10000/ 0.12 [ (1.12) ^ 10 -1 ]
= Rs 175483
21. 3 . Find the amount of an annuity of Rs 400 payable quarterly for
3 years at 16 % p.a .
Solution :- Here installment x= 400
Period is 1 quarter
16% p.a means 4% per Quarter
i.e 4 paise per rupee
Thus , i=0.04
N : number of installment
= 3 x 4
=12
To find amount A
We have
A=x/i [ (1 + I ) ^n -1 ]
23. We find more and more people purchasing vehicles and homes
by taking loan the bank . The repayment is generally made in
monthly installment over a period of two years , five years etc .
This ,monthly installments of repayment is called Equated
Monthly Installment (E.M.I )
The E. M . I is calculated using formula already given .
i.e P = x / i { 1- (1 + i)^ -n }
Amount of EMI
A= P(1 +r n /100)
24. 1. A two wheeler manufacturing company sells a motor cycle
costing Rs 44000 On installment basis by changing EMI Rs 4500
for 1 year . Find flat rate of interest .
Here A = 4500 x 12
= 54000,
P = 44000,
r = ? ,
n = 1
A= P(1 +r n /100)
54000= 44000(1 + r/100)
54/44 = 1 + r/100
r/100 = 54/44 -1
= 10/44
r = 1000/44
22.7
25. 2 .What is EMI of loan of RS 25000 if repaid in 4 years . At the rate
of interest 5 % p.a . On the outstanding amount at the beginning
of each year ?
Solution :- P=25000 , r=5 , n=4 years = 48 months
i = interest per rupee per month
= 12/1200
= 1/100
=0.01
Now P = x/i [ 1-( 1 + i)^ -n ]
25000 = x/0.01 [ 1- (1 + 0.01 ) ^ -48 ]
25000 = x/0.01 [ 1 –(1.01 )^ -48 ]
250 =x[ 1- 0.6203 ]
250 = x[ 0.3797]
x= 250 / 0.3797
x = 658.3459
26. 3 . Find The EMI on a loan of RS 3,00,00 to be paid in4 years at
12% p.a . On The Outstanding amount at the beginning of each
month .
4. Find EMI on a loan of 1,00,000 to be repaid in equal monthly
installments . Interest is charged at 12 % p.a on the loan
Outstanding at the beginning of each month and the time span in
5 years (1.01)^ 60 = 1.8199.
