As of September 2023, there have been 106 amendments of the Constitution of India since it was first enacted in 1950. There are two types of amendments to the constitution which are governed by article 368.
i. The first type includes amendments that can be effected by a Parliament of India by a prescribed 'Special Majority'.
ii. The second type of amendment includes those that require, in addition to such ""Special Majority"", ratification by at least one-half of the State Legislatures.
We say that it is our firm and solemn resolve to have an independent sovereign republic. India is bound to be sovereign, it is bound to be independent and it is bound to be a republic … Now, some friends have raised the question: “Why have you not put in the word ‘democratic’ here?” Well, I told them that it is conceivable, of course, that a republic may not be democratic but the whole of our past is witness to this fact that we stand for democratic institutions. Obviously we are aiming at democracy and nothing less than a democracy. What form of democracy, what shape it might take is another matter. The democracies of the present day, many of them in Europe and elsewhere, have played a great part in the world’s progress. Yet it may be doubtful if those democracies may not have to change their shape somewhat before long if they have to remain completely democratic. We are not going just to copy, I hope, a certain democratic procedure or an institution of a so-called democratic country. We may improve upon it. In any event whatever system of government we may establish here must fit in with the temper of our people and be acceptable to them. We stand for democracy. It will be for this House to determine what shape to give to that democracy, the fullest democracy, I hope. The House will notice that in this Resolution, although we have not used the word “democratic” because we thought it is obvious that the word “republic” contains that word and we did not want to use unnecessary words and redundant words, but we have done something much more than using the word. We have given the content of democracy in this Resolution and not only the content of democracy but the content, if I may say so, of economic democracy in this Resolution. Others might take objection to this Resolution on the ground that we have not said that it should be a Socialist State. Well, I stand for Socialism and, I hope, India will stand for Socialism and that India will go towards the constitution of a Socialist State and I do believe that the whole world will have to go that way.
How did defining India as a ‘republic’ enhance democratic governance?
Light Chemicals is an industrial paint supplier with presence in three locations: Mumbai, Hyderabad and Bengaluru. The sunburst chart below shows the distribution of the number of employees of different departments of Light Chemicals. There are four departments: Finance, IT, HR and Sales. The employees are deployed in four ranks: junior, mid, senior and executive. The chart shows four levels: location, department, rank and gender (M: male, F: female). At every level, the number of employees at a location/department/rank/gender are proportional to the corresponding area of the region represented in the chart.
Due to some issues with the software, the data on junior female employees have gone missing. Notice that there are junior female employees in Mumbai HR, Sales and IT departments, Hyderabad HR department, and Bengaluru IT and Finance departments. The corresponding missing numbers are marked u, v, w, x, y and z in the diagram, respectively.
It is also known that:
a) Light Chemicals has a total of 210 junior employees.
b) Light Chemicals has a total of 146 employees in the IT department.
c) Light Chemicals has a total of 777 employees in the Hyderabad office.

An investment company, Win Lose, recruit's employees to trade in the share market. For newcomers, they have a one-year probation period. During this period, the employees are given Rs. 1 lakh per month to invest the way they see fit. They are evaluated at the end of every month, using the following criteria:
1. If the total loss in any span of three consecutive months exceeds Rs. 20,000, their services are terminated at the end of that 3-month period,
2. If the total loss in any span of six consecutive months exceeds Rs. 10,000, their services are terminated at the end of that 6-month period.
Further, at the end of the 12-month probation period, if there are losses on their overall investment, their services are terminated.
Ratan, Shri, Tamal and Upanshu started working for Win Lose in January. Ratan was terminated after 4 months, Shri was terminated after 7 months, Tamal was terminated after 10 months, while Upanshu was not terminated even after 12 months. The table below, partially, lists their monthly profits (in Rs. ‘000’) over the 12-month period, where x, y and z are masked information.
Note:
• A negative profit value indicates a loss.
• The value in any cell is an integer.
Illustration: As Upanshu is continuing after March, that means his total profit during January-March (2z +2z +0) ≥
Rs.20,000. Similarly, as he is continuing after June, his total profit during January − June ≥
Rs.10,000, as well as his total profit during April-June ≥ Rs.10,000.
