TIME AND DISTANCE : IMPORTANT FORMULAS
Speed, Time and Distance:
Speed = Distance/Time
Time = Distance/ speed
Distance = (Speed x Time)
km/hr to m/sec conversion:
x km/hr = x X (5/18) m/sec.
m/sec to km/hr conversion:
x m/sec = x X (18/5) km/hr.
If the ratio of the speeds of A and B is a : b, then the ratio of the
the times taken by then to cover the same distance is 1/a : 1/b or b : a.
Suppose a man covers a certain distance at x km/hr and an equal distance at y km/hr. Then,
the average speed during the whole journey is: [2xy/(x + y)] km/hr.
Speed = Distance/Time
Time = Distance/ speed
Distance = (Speed x Time)
km/hr to m/sec conversion:
x km/hr = x X (5/18) m/sec.
m/sec to km/hr conversion:

PROBABILITY : IMPORTANT FORMULAS
Experiment:
An operation which can produce some well-defined outcomes is called an experiment.
Random Experiment:
An experiment in which all possible outcomes are know and the exact output cannot be predicted in advance, is called a random experiment.
Examples:
# Rolling an unbiased dice.
# Tossing a fair coin.
# Drawing a card from a pack of well-shuffled cards.
# Picking up a ball of certain colour from a bag containing balls of different colours.
Details:
[1] When we throw a coin, then either a Head (H) or a Tail (T) appears.
[2] A dice is a solid cube, having 6 faces, marked 1, 2, 3, 4, 5, 6 respectively. When we throw a die, the outcome is the number that appears on its upper face.
[3] A pack of cards has 52 cards.
It has 13 cards of each suit, name Spades, Clubs, Hearts and Diamonds.
Cards of spades and clubs are black cards.
Cards of hearts and diamonds are red cards.
There are 4 honours of each unit.
There are Kings, Queens and Jacks. These are all called face cards.
Sample Space:
When we perform an experiment, then the set S of all possible outcomes is called the sample space.
Examples:
[1] In tossing a coin, S = {H, T}
[2] If two coins are tossed, the S = {HH, HT, TH, TT}.
[3] In rolling a dice, we have, S = {1, 2, 3, 4, 5, 6}.
Event:
Any subset of a sample space is called an event.
Probability of Occurrence of an Event:
Let S be the sample and let E be an event.
Then, E S.
P(E) = n(E)/n(S)
Results on Probability:
[1] P(S) = 1
[2] 0 P (E) 1
[3] P() = 0
For any events A and B we have : P(A B) = P(A) + P(B) - P(A B)
If A denotes (not-A), then P(A) = 1 - P(A).
An operation which can produce some well-defined outcomes is called an experiment.
Random Experiment:

PARTNERSHIP: IMPORTANT FORMULAS
Partnership:
When two or more than two persons run a business jointly, they are called partners and the deal is known as partnership.
Ratio of Divisions of Gains:
When investments of all the partners are for the same time, the gain or loss is distributed among the partners in the ratio of their investments.
Suppose A and B invest Rs. x and Rs. y respectively for a year in a business, then at the end of the year:
(A's share of profit) : (B's share of profit) = x : y.
When investments are for different time periods, then equivalent capitals are calculated for a unit of time by taking (capital x number of units of time). Now gain or loss is divided in the ratio of these capitals.
Suppose A invests Rs. x for p months and B invests Rs. y for q months then,
(A's share of profit) : (B's share of profit)= xp : yq.
Working and Sleeping Partners:
A partner who manages the the business is known as a working partner and the one who simply invests the money is a sleeping partner.

RATIO AND PROPORTION: IMPORTANT FORMULAS
[1] Ratio:
The ratio of two quantities a and b in the same units, is the fraction a/b and we write it as a : b.
In the ratio a : b, we call a as the first term or antecedent and b, the second term or consequent.
Eg. The ratio 5 : 9 represents 5/9 with antecedent = 5, consequent = 9.
Rule: The multiplication or division of each term of a ratio by the same non-zero number does not affect the ratio.
Eg. 4 : 5 = 8 : 10 = 12 : 15. Also, 4 : 6 = 2 : 3.
[2] Proportion:
The equality of two ratios is called proportion.
If a : b = c : d, we write a : b :: c : d and we say that a, b, c, d are in proportion.
Here a and d are called extremes, while b and c are called mean terms.
Product of means = Product of extremes.
Thus, a : b :: c : d (b x c) = (a x d).
[3] Fourth Proportional:
If a : b = c : d, then d is called the fourth proportional to a, b, c.
Third Proportional:
a : b = c : d, then c is called the third proportion to a and b.
Mean Proportional:
Mean proportional between a and b is root of ab.
[4] Comparison of Ratios:
We say that (a : b) > (c : d) = a/b > c/d
Compounded Ratio:
The compounded ratio of the ratios: (a : b), (c : d), (e : f) is (ace : bdf).
[5] Duplicate Ratios:
Duplicate ratio of (a : b) is (a2 : b2).
Sub-duplicate ratio of (a : b) is (a : b).
Triplicate ratio of (a : b) is (a3 : b3).
Sub-triplicate ratio of (a : b) is (a1/3 : b1/3).
If a/b =c/d, then (a+b)/(a-b) = (c+d)/ (c-d)[componendo and dividendo]
[6] Variations:
We say that x is directly proportional to y, if x = ky for some constant k and we write, x is proportional to y.
We say that x is inversely proportional to y, if xy = k for some constant k and
we write, x is inversely proportional y.
The ratio of two quantities a and b in the same units, is the fraction a/b and we write it as a : b.
In the ratio a : b, we call a as the first term or antecedent and b, the second term or consequent.
Eg. The ratio 5 : 9 represents 5/9 with antecedent = 5, consequent = 9.
Rule: The multiplication or division of each term of a ratio by the same non-zero number does not affect the ratio.
Eg. 4 : 5 = 8 : 10 = 12 : 15. Also, 4 : 6 = 2 : 3.

Product of means = Product of extremes.
Thus, a : b :: c : d (b x c) = (a x d).
[3] Fourth Proportional:
If a : b = c : d, then d is called the fourth proportional to a, b, c.
Third Proportional:
a : b = c : d, then c is called the third proportion to a and b.
Mean Proportional:
Mean proportional between a and b is root of ab.
[4] Comparison of Ratios:

Duplicate ratio of (a : b) is (a2 : b2).
Sub-duplicate ratio of (a : b) is (a : b).
Triplicate ratio of (a : b) is (a3 : b3).
Sub-triplicate ratio of (a : b) is (a1/3 : b1/3).
