[Current Affairs] - What is One Rank, One Pension (OROP) Scheme

Be it PM's Independence Day Speech or Protests by Ex-Servicemen of Defence Forces, OROP(One Rank, One Pension Scheme) is one of the hottest topics the in recent days.

Let's see What is is ?

Timeline

• 2006: UPA government modified pension rules for defense services

• As a result, a serviceman retiring after 2006 would receive bigger pension than someone retired before 2006.

• Ex-Servicemen were annoyed at this Discrimination and demanded 'One Rank, One Pension'.

[Quantitative Aptitude/SBIPO/SSC/CLAT/GMAT/Placement Drives] - Speed,Distance and Time Part-1

One can always expect 2-3 questions from this topic in any competitive exam. The problems from this topic can be very complex in nature as it involves various logical concepts.Thus it becomes imperative to deeply understand the fundamentals of this chapter.

Note :

To solve any problem all units in the question must be uniform i.e. either all of them in m/s or km/hr.

Thus we must remember the conversion.

1 km/hr = 5 / 18 m/s                  and                               1 m/s = 18/5 km/hr


Questions based on these concepts :

Q1. Speed of Milkha Singh is 40km/hr and Speed of Forrest Gump is 30km/hr.What's the ratio of time taken by them to cover the same distance ?

Q2. Milkha takes half the time taken by Forrest to run the same distance. Forrest takes 2 hours.What is the speed of Milkha if the speed of Forrest is 20 Km/hr ?

Explanation : There is nothing much to explain in question one. In Q2, we can easily arrive at the Ratio of speeds of Milkha and Forrest is inversely proportional to the Raio of Time taken by them, which makes it 2 : 1.

Now Speed of Forrest is 20 km/hr which is 20 times 1 therefore, speed of Milkha should be 20 times 2 = 40 Km/hr (Ans).

[Interview/General Awareness/SBIPO/RBI] - Short Charticle on Social Security Schemes by Modi Government

[Quantitative Aptitude/SBIPO/SSC/CLAT/Placement Drives] - Percentages Tricks

Actually I should have started with this topic only as the concepts from this topic are heavily used in subsequent topics. It also plays a pivotal role in solving Data Interpretation questions.

I won't cover the basics further.Read them from some book and solve some questions.

To convert a fraction/ratio into percentage we multiply it by hundred.

1/2 = 1/2*100 =50 %

To solve percentage questions one must remember some factors as percentages.This is done to make calculations simple.

Explanation: If there is a increase or decrease by a fraction. Let Denominator be the base(original value) and numerator be increase/decrease.Obtain the new value by adding/subtracting the numerator to denominator as per the question.

Next step is to find the Multiplication factor between the Denominator and value given in the question. In this case it is 4 as 7*4=28.Multiply the same factor to the new value obtained and you get the increased/decreased final value.Here 8(New value) * 4 = 32 Ans.

[Quantitative Aptitude/SBIPO/SSC/Placement Drives] - Time and Work

Well this is the easiest chapter to start with and one can easily attempt questions without using Paper-Pen.

The approach to solve questions revolves around finding work done per unit time i.e. work done in 1 day or 1 year or 1 hour.It depends upon the time unit given in the question.

For e.g.

Q. PM Modi visits 54 countries in 3 years. How many countries will he visit in 5 years ?

In this question year is the unit of time.

3 years -------------- 54  countries
1 year  -------------- 54/3 = 18 countries (Efficiency) 

Once we have this number 18 we can easily find that in 5 years he can visit 18*5 = 90 Countries

Secondly, Efficiency is inversely proportional to time

i.e. if Modi is thrice efficient than Manmohan it means that to do a piece of work Manmohan takes thrice as much time as Modi.
