A Three-tier system is arranged i.e. Gram Panchayat, Panchayat Samiti and Zila Parishad.

Panchayati Samiti now functions as a system of governance in which gram panchayats are the basic units of local administration. The system has three levels: Gram Panchayat (village level), Mandal Parishad or Block Samiti or Panchayat Samiti (block level), and Zila Parishad (district level).

Newton’s laws are part of classical mechanics to understand the motion of objects. Newton presented his three laws of motion in 1687 in his ‘philosophiae Naturalis principia Mathematica’, usually called the Principia.

According to Newton’s first law:

If net force on a body is zero, if the body is at rest , it will remain at rest and if the body is moving with constant velocity, it will continue to do so.

The first law of Newton gives the definition of term inertia.

Inertia:- It is property of the body to resist the change in its state unless an external force is applied on it. There are three types of inertia:

(a) Inertia of rest- Here if the body is in rest, it will remain in rest unless an external force acts on it.

(b) Inertia of Motion- If the body is moving with a constant velocity then will remain moving with that velocity unless an external force cats on it.

(c) Inertia of direction- A body moving in particular direction will move in that direction unless a force acts on it.

Now coming to the question, here the bus is in the motion with constant velocity. Passenger seating on his seat in the bus will have inertia of motion as no net force acts on the passenger. But as soon as the bus stops the lower part of the body comes to rest instantaneously but the upper part of the body is still in motion due to inertia of motion. Therefore, the passenger will fall ahead.

The longitudinal extent of Tamil Nadu is 76°18' E to 80°20'E.

Hypopnea is related to sleep apnea and is a part of the same family of sleep disorders. In hypopnea, there is a decrease of airflow for at least 10 seconds in respirations, a 30-percent reduction in ventilation, and a decrease in oxygen saturation. It is overly shallow breathing or an abnormally low respiratory rate.

Thus, in hypopnea, the airway becomes partially obstructed.

The word ‘than’ after the blank is a major hint that a comparative degree should be filled in the blank. Therefore, 'better' is the only appropriate choice here.

She liked to be with him better than with the others, and when alone with him she sometimes laughed.

The correct sentence is- The man who jumped into the lake managed to swim ashore.

We use past perfect tense with simple past tense when the one activity finished much time before the second act. Here, jumping into the river and then swimming ashore happened simultaneously. Therefore, there is no need to use past perfect tense in the sentence and it must be kept in simple past.

The word 'summon' is a verb that means order someone to be present.

Of the given options, the only word that is similar in meaning is 'call for' which means to summon or request someone or something.

For eg: As I neared home, I could hear my mother calling for me.

In this type of question, first we need to calculate 1 hours work, then their collective work as,

A's 1 hour work is

B's 1 hour work is

(A+B)'s 1 hour work

So both will finish the work in hours

A complete work in = 5 days

A’s 1 - day work = 1/5

B complete work in = 5 days

B’s 1 - day work = 1/5

Both working together for 1 day= (1/5) + (1/5) =  (2/5)

∴ Time to complete the work together = (5/2) days

Nayan has 4 caps of 3 different colors in the given question.

In statement 1, Nayan has 2 white caps.

In statement 2, Nayan has 2 blue caps, but the question has 3 different colored caps.

In both statements, we do not know the color of all the caps.

∴ We can say that neither statement 1 nor statement 2 are sufficient.

I does not mention the day of the week on the birthday of either Arun or Sahil.

According to II, Sahil's sister was born on Wednesday and Sahil was born two days before Wednesday i.e. on Monday.

The logic followed here is:

C + 3 = F

F + 3 = I

I + 3 = L

Thus, "L" is the next term of the series.

The second sentence of the thirdparagraph reads, “In economics, productivity — the amount of economicvalue created for a given unit of input, such as an hour of labor — isa crucial indicator of growth and wealth creation.” In this context, theprimary purpose of the appositive (“the amount of economic value . . .such as an hour of labor”) is to define “productivity.”

In the first paragraph of the passage,Brynjolfsson and McAfee clearly state that technological advancessince the year 2000 have led to low job growth in the United States:“MIT business scholars Erik Brynjolfsson and Andrew McAfee haveargued that impressive advances in computer technology — fromimproved industrial robotics to automated translation services —are largely behind the sluggish employment growth of the last 10 to15 years.”

Starting Point: Start with placing F and J as, F sits opposite to the one who sits 2nd to the left of J which means both J and F are not sitting in the same row.

E and J are immediate neighbors. J faces south. F works in HP and sits at one of the extreme ends. A sits opposite to F.

So, E either sits to the right or left of J. So, we have 2 cases.

Case I: When E sits to the left of J in row 1:

Case II: When E sits to the right of J in row 1:

E sits opposite to the one who sits second to the right of the one who works in Tata. H works in HCL. Only one person sits between the one who works in Tata and the one who works in HCL. B works in Wipro and sits third to the right of the one who works in Infosys. B sits opposite to C. C sits to the immediate right of the one who works in IBM.

So, case II is rejected because E sits opposite to the one who sits 2nd to the right of the one works in Tata which is not possible in case II. Also, A must be working in Infosys so, that C sits immediate right of the one who works in IBM.

The one who works in LG sits opposite to G, who works in TCS. I does not work in Nokia. I does not work in IBM.

So, J must be working in LG so, that G sits opposite to the one who works in LG. Also, E works in Nokia and I works in Samsung.

The final arrangement is as follows:

E sits 3rd to the left of the one who works in Samsung.
