Static GK decides most of the General Awareness score in SSC exams. The CGL, CHSL and CPO notices describe it in almost the same words: questions on India and its neighbouring countries in History, Culture, Geography, the Economic Scene, General Policy and Scientific Research, and on everyday observation in its scientific aspect. The GD notice adds Sports, General Polity and the Indian Constitution, and the MTS notice lists Social Studies, General Science and Environmental Studies up to the 10th Standard. This page brings together GK24's GK notes and practice questions tagged for all five SSC exams. The notes follow a subject-wise syllabus, one topic per note in English and Hindi: Indian Polity, Indian History, Geography, Indian Economy, General Science, Environment and Ecology, Art and Culture, Computer, Sports, Awards and Honours, Books and Authors, Days and Dates, and Static GK. Each note is written as short facts and tables so that a topic can be revised in one sitting, and each ends with multiple-choice questions and explanations. The level is what changes between exams: read MTS and GD topics at Class 10 depth, CHSL at Class 12 depth, and CGL and CPO at graduate depth, where questions ask for the article number or the year rather than the broad idea. Start with Polity, History and Geography, which fill the most questions in past papers in GK24's reading, then move to the Economy and Science. After each note, solve its questions here and your exam's previous-year questions on its own page.
Which of the following is an example of a wedge?
A wedge is two inclined planes joined back to back, and an axe, a knife, a chisel and a nail all work on that principle: a force applied at the blunt end is turned into a much larger sideways force at the sharp edge, and the thinner and longer the…
Read the full explanation →The distance between two consecutive threads of a screw is called its:
The pitch of a screw is the distance between two consecutive threads measured along its axis, and it is also the distance through which the screw advances in one complete turn; the velocity ratio of a screw is the circumference of the circle described by the handle divided by the…
Read the full explanation →An inclined plane is 10 metres long and 2 metres high. What is its velocity ratio?
The velocity ratio of an inclined plane is the length of the slope divided by its vertical height, because the load is pushed along the whole slope while it is raised only through the height; here ten divided by two gives five, so in the ideal case an effort of…
Read the full explanation →What is the velocity ratio of a single fixed pulley?
In a single fixed pulley the rope that is pulled down moves exactly as far as the load rises, so the distance moved by the effort equals the distance moved by the load and the velocity ratio is one; the pulley gives no gain in force and is used only…
Read the full explanation →A pair of forceps or sugar tongs is an example of which class of lever?
In a pair of tongs the joint is the fulcrum, the hand presses somewhere in the middle of the arms and the object held lies at the far end, so the effort is between the fulcrum and the load; the effort arm is shorter than the load arm, the mechanical…
Read the full explanation →A wheelbarrow is an example of which class of lever?
In a wheelbarrow the wheel acts as the fulcrum, the load sits in the tray between the wheel and the hands, and the effort is applied at the handles, which is the arrangement of a second class lever; because the effort arm is always longer than the load arm, its…
Read the full explanation →Which of the following mechanical devices efficiently distributes or multiplies loads with little effort?
A lever is a rigid bar turning about a fulcrum, and by the principle of moments the load multiplied by the load arm equals the effort multiplied by the effort arm, so a long effort arm lets a small effort balance a large load; this is the simplest way of…
Read the full explanation →The velocity ratio of a simple machine is the ratio of distance travelled by the ________ to the distance travelled by the ________ in the machine.
Velocity ratio is defined as the distance moved by the effort divided by the distance moved by the load in the same interval of time, and because it depends only on the design of the machine it does not change with friction, unlike the mechanical advantage.
Read the full explanation →Find the efficiency of a pulley system which has a mechanical advantage of 2.5 and where the load lifts by 2.5 metres on pulling the rope by 10 m.
The velocity ratio is the distance moved by the effort divided by the distance moved by the load, that is ten divided by two point five, which is four.
Read the full explanation →The effort applied to move a load is 15 units and the mechanical advantage is observed to be 3. Find the load.
Mechanical advantage is defined as the load divided by the effort, so the load is the mechanical advantage multiplied by the effort, that is three multiplied by fifteen, which gives forty-five units.

To contest a Lok Sabha seat, a person must be a citizen and an elector, but the name can be on the roll of any constituency in the country.
Read the full explanation →In which of the following areas can GPS technology be used ? 1. Mobile phone operations 2. Banking operations 3. Controlling the power grids Select the correct answer using the code given below:
Besides location, GPS satellites broadcast extremely precise time, and mobile networks, banks and power grids all depend on that timing.
Read the full explanation →Consider the following pairs : Craft — Heritage of 1. Puthukkuli shawls — Tamil Nadu 2. Sujni embroidery — Maharashtra 3. Uppada Jamdani saris — Karnataka Which of the pairs given above is/are correct ?
Puthukkuli shawls come from Tamil Nadu, but Sujni embroidery belongs to Bihar and Uppada Jamdani saris to Andhra Pradesh.
Read the full explanation →"Leaf litter decomposes faster than in any other biome and as a result the soil surface is often almost bare. Apart from trees, the vegetation is largely composed of plant forms that reach up into the canopy vicariously, by climbing the trees or growing as epiphytes, rooted on the upper branches of trees." This is the most likely description of
Constant heat and heavy rain make decomposition fastest there, and climbers and epiphytes are its typical plant forms. Tropical rain forests lie near the equator, in the Amazon, the Congo basin and South-East Asia, with temperatures around 27°C and rain in every month.
Read the full explanation →Consider the following statements : 1. In a seismograph, P waves are recorded earlier than S waves. 2. In P waves, the individual particles vibrate to and fro in the direction of wave propagation whereas in S waves, the particles vibrate up and down at right angles to the direction of wave propagation. Which of the statements given above is/are correct?
P waves are the fastest seismic waves and reach a seismograph first, and they move particles along the direction of travel, while S waves move them at right angles to it.

Periyar launched the Self-Respect Movement in the Madras Presidency in 1925 to fight caste discrimination and Brahmin dominance. Periyar had left the Congress after he felt it did little for non-Brahmins.

Lebanon and Syria have coastlines on the eastern Mediterranean; Jordan and Iraq do not. The eastern shore of the Mediterranean, called the Levant coast, runs from Turkey in the north through Syria, Lebanon and Israel to the Gaza Strip and Egypt.

The Constituent Assembly would have members nominated by the Provincial Assemblies as well as the Princely States. 2. Any Province, which is not prepared to accept the new Constitution would have the right to sign a separate agreement with Britain regarding its future status. Which of the statements given above is/are correct?
The Cripps proposals let any province stay out of the new Union and deal with Britain separately, but the provincial members of the Constituent Assembly were to be elected, not nominated.
