COMMERCIAL ARITHMETIC

Compound Interest:

A = P ; when the interest is compounded half-yearly.

A = P , If the time is 2 years and the rate is compounded yearly.

For Growth: V = V0 , V0 = Initial Value, V = Final Value

For Depreciation: V = V0

Sales Tax and Value Added Tax:

The price at which an Article is marked : List Price/Marked Price/Printed Price/Quoted Price

Sale Price = M.P. – Discount, Discount is calculated on M.P.

Sales Tax is calculated after deducting the discount (on the discounted price).

Sales Tax =

Sale-price = C.P.

Sale-price = C.P.

Sale-price = M.P.

VAT paid by a person =

VAT = Tax recovered(charged) on the sale – Tax paid on the purchase

A = P + I

S.I. =

S.I. for 1st year = C.I. for 1

st year

C. I. for (n + 1) year = C.I. of nth

year + Int. on it for 1 year ; R% = %, where T = 1yr

Amount in (n + 1) year = Amount in nth

year + Int. on it for 1 year; R% = %

A = P

C.I. = P

A = P ; when rates for successive years are different.

Banking:

1. SB Account:

a. Withdrawal = Debit

b. Deposit = Credit

c. Steps for calculation of interest:

i. Find the minimum balance of each month between 10th

day and the last day.

ii. Add all the balances. This is the Equivalent Monthly Principal for 1 month.

iii. Calculate the SI on the Equivalent Monthly Principal with T = years.

iv. No interest is paid for the month in which the account is closed.

v. If the Amount Received on closing is asked, add the interest to the LAST BALANCE

and not to the Equivalent Monthly Principal.

2. RD Account:

a. I = ; T = years ; P = monthly deposit, n = no. of months, r = rate%

b. M.V. = P ; Maturity Value = Total deposit (monthly deposit nterest

Shares and Dividend:

The total money invested by the company is called its capital stock.

The capital stock is divided into a number of equal units. Each unit is a called a share.

Nominal Value is also called Register Value, Printed Value, and Face Value.

The FV of a share always remains the same, while its MV goes on changing.

The part of the profit of a company which is distributed amongst the shareholders is known as

dividend.

If the MV of the share is same as its NV, the share is said to be at par.

If the MV of the share is greater than NV, the share is said to be at premium.

If the MV of the share is less than NV, the share is said to be at discount.

No. of shares =

Dividend = NV No. of shares ; total annual income = DNN or DFN

Return % = 100 %

Rate of dividend% NV = Return % MV ; DN = PM

% increase in return on original investment = 100 %

% increase in return = 100 %

ALGEBRA

Linear Inequations:

The signs are called signs of inequality.

On transferring +ve term becomes –ve and vice versa.

If each term is multiplied or divided by +ve number, the sign of inequality remains the same.

The sign of inequality reverses:

If each term is multiplied or divided by same negative number.

If the sign of each term on both the sides of an inequation is changed.

On taking reciprocals of both sides, in case both the sides are positive or negative.

Always, write the solution set for the inequation, e.g.,{x : x 3, x N}, solution set = {1, 2, 3}

To represent the solution on a number line:

Put arrow sign on both the ends of the line and keep extra integers beyond the range.

Use dark dots on the line for each element of N, W and Z.

For Q, R: mark range with solid circle (for ), hollow circle (for < and >.)

“and” means Intersection ( only common elements of the sets).

“or” means Union(all elements of the sets without repetition).

Quadratic Equations:

1. Quadratic equation is an equation with one variable, the highest power of the variable is 2.

2. Some useful results:

a) (a + b)2 = a

2 + b

2 + 2ab

b) (a - b)2 = a

2 + b

2 - 2ab

c) a 2 – b

2= (a + b) (a – b)

d) (a + b)2 - (a - b)

2 = 4ab

e) (a + b)3 = a

3 + b

3 + 3ab(a + b)

f) (a - b)3 = a

3 - b

3 - 3ab(a - b)

5

Ratio and Proportion:

A ratio is a comparison of the sizes of two or more quantities of the same kind by division. Since ratio

is a number, so it has no units.

To find the ratio between two quantities, change them to the same units.

To compare two ratios, convert them into like fractions.

In the ratio, a : b, a is called antecedent and b is called consequent.

= = =

Compound ratio of a : b and c : d is (a × c) : (b × d)

Duplicate ratio of a : b is a2 : b

2

Triplicate ratio of a : b is a3 : b

3

Sub-duplicate ratio of a : b is :

g) (a + b + c)2 = a

2 + b

2 + c

2 + 2ab + 2bc + 2ca

h) a3 + b

3 + c

3 – 3abc = (a + b + c) (a

2 + b

2 + c

2 – ab – bc – ca)

3. Steps for solving quadratic equation by factorization:

a. Clear all fractions and brackets if necessary.

b. Bring it to the form ax2 + bx + c = 0 by transposing terms.

c. Factorize the expression by splitting the middle term as a sum of product of a and c.

4. Discriminant (D) =

a. if D 0, then the roots are real and unequal

b. if D = 0, then the roots are real and equal

c. if D 0, then the roots are not real (imaginary).

5. The roots of the quadratic equation ax2 + bx + c = 0 ; a 0 can be obtained by using the formula:

x =

6

Matrices:

A rectangular arrangement of numbers, in the form of horizontal (rows) and vertical lines (columns)

is called a matrix. Each number of a matrix is called its element. The elements of a matrix are

enclosed in brackets [ ].

The order of a matrix = No. of rows × No. of columns

Row matrix: Only 1 row.

Column matrix: Only 1 column.

Sub-triplicate ratio of a : b is :

Reciprocal ratio of a : b is b : a

Proportion- An equality of two ratios is called a proportion. Written as: a : b :: c : d or =

Product of extreme terms = product of middle terms, if a, b, c, d are in proportion then ad = bc

Continued Proportion- a : b :: b : c or a : b = b : c ; mean proportion (b) =

Invertendo - If a : b = c : d, then b : a = d : c

Alternendo - If a : b = c : d, then a : c = b : d

Componendo - If a : b = c : d, then a + b : b = c + d : d

Dividendo - If a : b = c : d, then a - b : b = c - d : d

Componendo and Dividendo - If a : b = c : d, then a + b : a – b = c + d : c – d

Remainder and Factor Theorem:

1. If f (x) is a polynomial, which is divisible by (x – a), a R, then the remainder is f (a).

2. If the remainder on dividing a polynomial f (x) by (x – a), f (a) = 0, then (x - a) is a factor of f (x).

3. When f (x) is divided by (ax + b), then remainder is f , a 0

4. When f (x) is divided by (ax - b), then remainder is f , a 0

Mode is the variate which has the maximum frequency.

The class with maximum frequency is called the modal class.

To estimate mode from histogram: draw two straight lines from the corners of the rectangles on either

sides of the highest rectangle to the opposite corners of the highest rectangle. Through the point of

intersection of the two straight lines, draw a vertical line to meet the x-axis at the point M (say). The

variate at the point M is the required mode.

Arithmetic mean on non tabulated data: =

Arithmetic mean on tabulated data(Direct Method): = ; x = mid value (C.I.)

Arithmetic mean by Short-cut Method: = + A ; A = assumed mean , d = x – A

Arithmetic mean by Step-deviation Method: = + A ; i = class width , t =

If n is odd, Median = term

For raw data, if n is even, Median =

For tabulated data, Median = if n is even and Median = if n is odd.

Lower quartile, Q1 = term if n is odd and term if n is even

Probability:

Probability is a measure of uncertainty.

An Experiment is an action which results in some (well-defined) outcomes.

Sample space is the collection of all possible outcomes of an experiment. n(S)

An Event is a subset of the sample space associated with a random experiment. n(E)

An Event occurs when the outcome of an experiment satisfies the condition mentioned in the event.

The outcomes which ensure the occurrence of an event are called favourable outcomes to that event.

The probability of an event E, written as P(E), is defined as P (E) =

P(E) =

The value of probability is always between 0 and 1.

The probability of sure (certain) event is 1.

The probability of an impossible event is 0.

An elementary event is an event which has one (favourable) outcome from the sample space.

A Compound event is an event which has more than one outcome from the sample space.

If E is an event, then the event „not E‟ is complementary event of E and denoted by .

0 1

P(E) + P( ) = 1

In a pack (deck) of playing cards, there are 52 cards which are divided into 4 suits of 13 cards each –

spades ( ), hearts ( ), diamonds ( ) and clubs ( ). Spades and clubs are black in colour,

while hearts and diamonds are of red colour. The cards in each suit are ace, king, queen, jack, 10, 9,

8, 7, 6, 5, 4, 3, 2. Kings, queens and jacks are called face (picture/court) cards. The cards bearing

number 10, 9, 8, 7, 6, 5, 4, 3, 2 are called numbered cards. Thus a pack of playing cards has 4 aces, 12

face cards and 36 numbered cards. The aces together with face cards (= 16). are called cards of

honour.

When a coin is tossed, it may show head (H) up or tail (T) up. Thus the outcomes are: {H, T}.

When two coins are tossed simultaneously, then the outcomes are: {HH, HT, TH, TT}. [n(S) = 2n]

When a die is thrown once the outcomes are: {1, 2, 3, 4, 5, 6}. [n(S) = 6n]

When two dice are thrown simultaneously, then the outcomes are: {(1, 1),(1, 2)…….(6, 6)}.
