ALL IMPORTANT FORMULAS FOR COMPETITIVE EXAMS SSC BANK PO

ALL IMPORTANT FORMULAS

Some Useful Chapter wise Formulas : Like & Share Post
==============================================


1. Sum of first n natural numbers = n(n+1)/2
2. Sum of the squares of first n natural numbers = n(n+1)(2n+1)/6
3. Sum of the cubes of first n natural numbers = [n(n+1)/2]^2
4. Sum of first n natural odd numbers = n^2
5. Average = (Sum of items)/Number of items
Arithmetic Progression (A.P.):
==========================
An A.P. is of the form a, a+d, a+2d, a+3d, …
where a is called the ‘first term’ and d is called the ‘common difference’
1. nth term of an A.P. tn = a + (n-1)d
2. Sum of the first n terms of an A.P. Sn = n/2[2a+(n-1)d] or Sn = n/2(first term + last term)
Geometrical Progression (G.P.):
============================
A G.P. is of the form a, ar, ar2, ar3, …
where a is called the ‘first term’ and r is called the ‘common ratio’.
1. nth term of a G.P. tn = arn-1
2. Sum of the first n terms in a G.P. Sn = a|1-rn|/|1-r|
Permutations and Combinations :
===============================
nPr = n!/(n-r)!
nPn = n!
nP1 = n
nCr = n!/(r! (n-r)!)
nC1 = n
nC0 = 1 = nCn
nCr = nCn-r
nCr = nPr/r!
Number of diagonals in a geometric figure of n sides = nC2-n
Tests of Divisibility :
=======================
A number is divisible by 2 if it is an even number.
A number is divisible by 3 if the sum of the digits is divisible by 3.
A number is divisible by 4 if the number formed by the last two digits is divisible by 4.
A number is divisible by 5 if the units digit is either 5 or 0.
A number is divisible by 6 if the number is divisible by both 2 and 3.
A number is divisible by 8 if the number formed by the last three digits is divisible by 8.
A number is divisible by 9 if the sum of the digits is divisible by 9.
A number is divisible by 10 if the units digit is 0.
A number is divisible by 11 if the difference of the sum of its digits at odd places and the sum of its digits at even places, is divisible by 11.
H.C.F and L.C.M :
H.C.F stands for Highest Common Factor. The other names for H.C.F are Greatest Common Divisor (G.C.D) and Greatest Common Measure (G.C.M).
The H.C.F. of two or more numbers is the greatest number that divides each one of them exactly.
The least number which is exactly divisible by each one of the given numbers is called their L.C.M.
Two numbers are said to be co-prime if their H.C.F. is 1.
H.C.F. of fractions = H.C.F. of numerators/L.C.M of denominators
L.C.M. of fractions = G.C.D. of numerators/H.C.F of denominators
Product of two numbers = Product of their H.C.F. and L.C.M.
PERCENTAGES :
================
If A is R% more than B, then B is less than A by R / (100+R) * 100
If A is R% less than B, then B is more than A by R / (100-R) * 100
If the price of a commodity increases by R%, then reduction in consumption, not to increase the expenditure is : R/(100+R)*100
If the price of a commodity decreases by R%, then the increase in consumption, not to decrease the expenditure is : R/(100-R)*100
PROFIT & LOSS :
======================
Gain = Selling Price(S.P.) – Cost Price(C.P)
Loss = C.P. – S.P.
Gain % = Gain * 100 / C.P.
Loss % = Loss * 100 / C.P.
S.P. = (100+Gain%)/100*C.P.
S.P. = (100-Loss%)/100*C.P.
If CP(x), Gain(y), Gain%(z). Then y = x*z/100. [Same in case of Loss]
RATIO & PROPORTIONS:
==========================
The ratio a : b represents a fraction a/b. a is called antecedent and b is called consequent.
The equality of two different ratios is called proportion.
If a : b = c : d then a, b, c, d are in proportion. This is represented by a : b :: c : d.
In a : b = c : d, then we have a* d = b * c.
If a/b = c/d then ( a + b ) / ( a – b ) = ( c + d ) / ( c – d ).
TIME & WORK :
===================
If A can do a piece of work in n days, then A’s 1 day’s work = 1/n
If A and B work together for n days, then (A+B)’s 1 days’s work = 1/n
If A is twice as good workman as B, then ratio of work done by A and B = 2:1
PIPES & CISTERNS :
=====================
If a pipe can fill a tank in x hours, then part of tank filled in one hour = 1/x
If a pipe can empty a full tank in y hours, then part emptied in one hour = 1/y
If a pipe can fill a tank in x hours, and another pipe can empty the full tank in y hours, then on opening both the pipes,
the net part filled in 1 hour = (1/x-1/y) if y>x
the net part emptied in 1 hour = (1/y-1/x) if x>y
TIME & DISTANCE :
=======================
Distance = Speed * Time
1 km/hr = 5/18 m/sec
1 m/sec = 18/5 km/hr
Suppose a man covers a certain distance at x kmph and an equal distance at y kmph. Then, the average speed during the whole journey is 2xy/(x+y) kmph.
PROBLEMS ON TRAINS :
=========================
Time taken by a train x metres long in passing a signal post or a pole or a standing man is equal to the time taken by the train to cover x metres.
Time taken by a train x metres long in passing a stationary object of length y metres is equal to the time taken by the train to cover x+y metres.
Suppose two trains are moving in the same direction at u kmph and v kmph such that u>v, then their relative speed = u-v kmph.
If two trains of length x km and y km are moving in the same direction at u kmph and v kmph, where u>v, then time taken by the faster train to cross the slower train = (x+y)/(u-v) hours.
Suppose two trains are moving in opposite directions at u kmph and v kmph. Then, their relative speed = (u+v) kmph.
If two trains of length x km and y km are moving in the opposite directions at u kmph and v kmph, then time taken by the trains to cross each other = (x+y)/(u+v)hours.
If two trains start at the same time from two points A and B towards each other and after crossing they take a and b hours in reaching B and A respectively, then A’s speed : B’s speed = (√b : √a)
SIMPLE & COMPOUND INTERESTS :
===================================
Let P be the principal, R be the interest rate percent per annum, and N be the time period.
Simple Interest = (P*N*R)/100
Compound Interest = P(1 + R/100)^N – P
Amount = Principal + Interest
when rate of interest time n principal are constant den principal=(C.I.-S.I.)*(100/R)^N
LOGORITHMS :
====================
If a^m = x , then m = loga(x).
Properties :
logx(x) = 1
logx(1) = 0
loga(x*y) = loga(x) + loga(y)
loga(x/y) = log ax – log ay
loga(x) = 1/logx(a)
loga(x^p) = p(loga(x))
loga(x) = logb(x)/logb(a)
Note : Logarithms for base 1 does not exist.
AREA & PERIMETER :
===================
Shape Area Perimeter
Circle ∏ (Radius)2 2∏(Radius)
Square (side)2 4(side)
Rectangle length*breadth 2(length+breadth)
Area of a triangle = 1/2*Base*Height or
Area of a triangle = √ (s(s-(s-b)(s-c)) where a,b,c are the lengths of the sides and s = (a+b+c)/2
Area of a parallelogram = Base * Height
Area of a rhombus = 1/2(Product of diagonals)
Area of a trapezium = 1/2(Sum of parallel sides)(distance between the parallel sides)
Area of a quadrilateral = 1/2(diagonal)(Sum of sides)
Area of a regular hexagon = 6(√3/4)(side)2
Area of a ring = ∏(R2-r2) where R and r are the outer and inner radii of the ring.
Area of a circle=πr^2 or πd^2/4
Area of semi-circle=πr^2/2
Area of a quadrant of a circle=πr^2/4
Area enclosed by two concentric circles=π(R^2-r^2)
Area of a sector=Ɵ/180 degree *πr
No of revolutions completed by a rotating wheel in 1 minute=distance moved in 1 minute/circumference
VOLUME & SURFACE AREA :
============================
* Cube :
Let a be the length of each edge. Then,
Volume of the cube = a3 cubic units
Surface Area = 6a2 square units
Diagonal = √ 3 a units
* Cuboid :
Let l be the length, b be the breadth and h be the height of a cuboid. Then
Volume = lbh cu units
Surface Area = 2(lb+bh+lh) sq units
Diagonal = √ (l2+b2+h2)
* Cylinder :

HOW TO FIND SQUARE ROOT AND CUBE ROOT OF A NUMBER IBPS BANK MATERIAL

HAPPY READING





HI FRIENDS MANY OF US KNOW DIFFERENT METHODS AND PROCEDURES FOR FINDING SQUARE ROOT AND CUBE ROOT OF A NUMBER. I KNOW YOU ALL ARE GENIUS IN DOING SO , HERE I TO AM GOING TO SHOW YOU VERY SIMPLE WAY OF CALCULATING SQUARE ROOT AND CUBE ROOT OF A NUMBER.''








HMM. YES I THINK ITS REALLY INTERESTING RIGHT TO KNOW SHORTCUTS.

IN BANKING EXAMS "TIME MANAGEMENT" IS AN IMPORTANT FACTOR WHICH DETERMINES YOUR SUCCESS SO IN THIS REGARD PEOPLE WHO WANNA BE FIRST ALWAYS IN THEIR MIND CAN EASILY ACHIEVE IT.

THE ABOVE THINGS CAN HAPPEN IF YOU KNOW SHORT-CUTS.

MORE THE PRACTICE YOU YOURSELF WILL FIND MORE NO OF SHORT-CUTS





OK NOW LETS SEE HOW TO FIND SHORTCUTS FOR FINDING SQUARE ROOT AND CUBE
ROOT OF ANY NUMBER



SQUARE ROOT:

QUESTION : EXAMPLE FIND THE SQUARE ROOT OF 2116


STEP1: SEE REMEMBER SQUARE MEANS VALUE 2 AND CUBE MEANS VALUE 3 ..SO TO 

CALCULATE SQUARE ROOT OF 2116 ....TAKE LAST TWO DIGITS (REMEMBER IN SQUARE 

ROOT WE HAVE TO TAKE LAST TWO DIGITS AND CUBE ROOT LAST THREE DIGITS TO 

CONSIDER) SO HERE WE TAKE 16 ...IN 2116 


STEP 2: 16 MEANS SEE LAST DIGIT 6 SO ...6 COMES IN EITHER 4 SQUARE OR 6 SQUARE..SO 

LAST NUMBER IS EITHER 4 OR 6.. KEEP IT IN MIND



STEP 3: NOW TAKE ANOTHER TWO DIGITS FROM 2116 ,,,IE; 21  .SUPPOSE IF WE TAKE 

2SQUARE=4, 3 SQUARE=9, 4 SQUARE=16, AND SEE CAREFULLY 5SQUARE=25 I EXCEEDS 

21..SO TAKE 4 SQUARE ...ONLY

STEP5:SO ANSWER IS EITHER 46 OR 44 

ANY CONFUSION: SEE ABOVE STEPS CAREFULLY AND EASILY YOU CAN DO NEXT TIME 

WHEN U PRACTICE MORE YOU WILL SEE AND SAY THE ANSWER.


STEP6: OUT OF 44 AND 46 WHICH IS THE RIGHT ANSWER.



STEP 7: ALWAYS TAKE MIDDLE NUMBER IN SERIES 40 TO 49..IE; 45 OR ALWAYS TAKE 

NUMBER IN SERIES OF OUR ANSWER IE; 40 TO 49 ENDING WITH 5.


WHY WE CONSIDER ONLY ENDING WITH 5 BECAUSE ITS VERY EASY TO FIND OUT ANSWER 

USING THIS

SO ANY NUMBER ENDING WITH 5 

SHOERTCHUT IS 

45 SQUARE =  4 MULTIPLIED BY ITS NEXT NUMBER AND 5 SQAURE IN UNIT DIGIT PLACE


                          TENS DIGIT PLACE                                                           UNIT DIGIT  PLACE

                          4 X 5=20                                                                               5X5=25

SO 45 SQUARE =2025


LAST STEP:

DECIDING ANSWER BY SEEING 45 SQUARE

WE NEED TO FIND SQUARE OF 2116 .. SO 45 SQAURE =2025 SO 2116 IS GREATER THAN 2116

HENCE OUR ANSWER-46






I AM GOING TO POST CUBE ROOT SEPARATELY IN DIFFERENT POST...HAPPY READING
