Basics of Profit and Loss-Part1

Welcome to  www.job-updates.com First of all welcome to  www.job-updates.com   and we are providing all job updates, jobs information, shortcuts or tricks on  Aptitude ( Number series ,  simplification ,  time and work ,  time and distance ,  time and speed ),  reasoning, General Knowledge, as well as current affairs. Profit and Loss Basic Definitions and Formulas Cost price (C.P.): Buying price. Selling price (S.P.): sales Price. Profit/Gain: If the selling price is more than the cost price, the difference between them is the profit occurred. Formula:  Profit/ Gain = S.P. – C.P. Loss: If the selling price is less than the cost price, the difference between them is the loss occurred. Formula:  Loss = Cost price (C.P.) – Selling Price (S.P.) Profit or Loss is always calculated on the cost price. Marked price: This is the price marked as the selling price on an article, also known as the listed price. Discount or Rebate: This is the reduction in price offered on the marked or liste

basics of simplification for SSC UPSC IBPS

Welcome to  www.job-updates.com First of all welcome to  www.job-updates.com   and we are providing all job updates, jobs information, shortcuts or tricks on Aptitude ( Number series , simplification , time and work , time and distance , time and speed ), reasoning, General Knowledge, as well as current affairs. Simplification Step 1:  Parts of the expression enclosed in ‘Brackets’ must be solved first. Inside the brackets, once again BODMAS rules apply! Step  2:  The mathematical operators ‘of’ and ‘order’ must be solved next. ‘Of’ means part of and is solved by substituting with a multiplication sign. ‘Order’ is the same as exponent. Powers are solved after brackets. Powers also include roots. Step 3:  Next, the parts of the equation that contain ‘Division’ and ‘Multiplication’ are calculated. Step 4:  Last but not least, the parts of the equation that contain ‘Addition’ and ‘Subtraction’ should be calculated. Here is an example, to help you understand the BODMAS rule concept. E

how to solve five digit Square IBPS

how to solve five digit Square in less time First of all welcome to www.job-updates.com   and we are providing all job updates, jobs information, shortcuts or tricks on Aptitude(Number series, simplification, time and work, time and distance, time and speed), reasoning, General Knowledge, as well as current affairs. Now we will go to the Topic How to square a number easily Similer topic  how-to-cube-number-in-just-5secs First we are starting this topic we just learn three basic formula's for this topic (A+B)^2             =(A^2)+(B^2)+(2*A*B) (A+B)^2             =(A^2)+(B^2)-(2*A*B) (A^2)-(B^2)       =(A+B)(A-B) Now we will practice some problems on this Based on Formala -1 Ex:-  (102)^2=? Ans)    According to Formula we will devide 102 into  100+2         (102)^2         =  (100+2)^2                               =  (100)^2+(2)^2+(2*100*2)                               =  10000+4+400           (102)^2         =  10404       Like that we can solve 5-disit number also Based on For

Viral Aptitude Questions in japan & 60% failed to answer You?

Viral maths Basics rules of Aptitude Do you know the Basic fundmentals of Aptitude  ? The question Which is viral in Japan is Q) 9-3/(1/3)+1=? Ans)  Before going to the answer we just know about basic fundamentals of aptitude         We need to apply BODMAS rule to solve the equation.. which is                                                                          B      -    Bracket                                O      -    of                               D      -     Division                               M     -      Multiplication                               A      -      Addition                               S       -     Substraction we need to follow the above Priority to solve            9-3(1/3)+1   =>      9-9+1                           (Assume 3/(1/3)  =>  (3/1)/(1/3)    => 9/1  =>9                                   =0+1                                    =1 Example 2: 2.  5+63/9+2-12/3=? Ans )      first we need to apply BODMAS rule                   =

Average shorcuts part-1

Average  short cuts for all exams Welcome to job-updates.com Average  shortcuts- part-1 Time,speed and Distance shortcuts  Basics 1) There is a relationship between speed, distance and time:            Speed   = Distance / Time OR           Distance = Speed* Time 2) Average Speed = 2xy / x+y             where x km/hr is a speed for certain distance and y km/hr is a speed at         for same distance covered. **** Remember that average speed is not just an average of two speeds i.e. x+y/2. It is equal to 2xy / x+y 3) Always remember that during solving questions units must be same. Units can be km/hr, m/sec etc.          **** Conversion of km/ hr to m/ sec and m/ sec to km/ hr          x km/ hr = (x* 5/18) m/sec i.e. u just need to multiply 5/18           Similarly, x m/sec = (x*18/5) km/sec 4) As we know, Speed = Distance/ Time. Now, if in questions Distance is constant then speed will be inversely proportional to time i.e. if speed increases ,time taken will decrease and vice ve

Time and speed shortcuts-Part 1

Time, Speed and Distance Time and speed shortcuts-Part 1 Basics:       Speed     =  Distance / Time       Time       =   Distance / Speed      Distance  =   Speed * Time For conversion of Km/hr to m/sec and as well as m/sec to km/hr For km/hr to m/sec    =  we need multiply with 5/18 For m/sec to km/hr    =  we need multiply with 18/5 If u need clear info about conversion you can comment below Ex:- 1. A person crosses a 600 m long street in 5 minutes. what is his speed in km/hr? Ans:        D= 600m        T= 5min        S= ? in km/hr   In this, we can't do the direct calculation because speed in meters and Time in minutes so we need to convert anyone either speed into km or Time into sec or hr     Time = 5*60                       = 300sec     Speed=Distance/Time                          = 600/5                        = 120                        = 2 m/s  But this is not answer for the above question this is the mistake that most of the people doing in exams Because it is m/sec
