SSC CGL GK Questions 2026

The correct answer is C, 500 GW by 2030, the first of the five Panchamrit commitments placed before COP26 in Glasgow in 2021, the others being half of India's energy requirement from renewables by 2030, a billion tonnes off projected emissions by 2030, a 45 per cent cut in the…

The Union Budget for that year announced the intention, the Government published a Sovereign Green Bonds framework in 2022, and the Reserve Bank of India auctioned the first tranche on the Government's behalf in January 2023, with the proceeds earmarked for renewable energy, clean transport, energy efficiency, sustainable water management…

Each designated consumer in an energy-intensive industry such as cement, steel, aluminium, fertiliser or thermal power is given a specific energy consumption target; a plant that beats its target earns ESCerts, and a plant that misses it must buy them, which the power exchanges make possible.

In the same scheme the Grid Controller of India keeps the registry and the Central Electricity Regulatory Commission regulates trading.

The Energy Conservation (Amendment) Act, 2022 inserted the power for the Central Government to specify a Carbon Credit Trading Scheme, which is why the market sits with the Ministry of Power and its Bureau of Energy Efficiency rather than with the environment ministry.

The correct answer is C, COP26 in Glasgow, held in 2021, where India placed a five-part pledge known as the Panchamrit before the conference: 500 GW of non-fossil energy capacity by 2030, half its energy requirement from renewables by 2030, a cut of one billion tonnes in projected emissions by…

It holds all the market machinery of the Paris Agreement: Article 6.2 lets two countries cooperate bilaterally and transfer Internationally Transferred Mitigation Outcomes with a corresponding adjustment so the same tonne is not counted twice, Article 6.4 establishes a centralised crediting mechanism supervised by a United Nations body as the…

India hosted a very large number of such projects and was among the world's biggest sellers of CERs.

Adopted in 1997 at COP3 in Japan and in force from 2005, it set binding emission targets for developed countries and gave them three flexible mechanisms to meet them; the Clean Development Mechanism, under Article 12, let a developed country fund an emission-reduction project in a developing country and claim…

The tonne is the standard trading unit in every carbon market, compliance or voluntary, and it is written as 1 tCO2e. The word equivalent matters: gases other than carbon dioxide are converted into carbon dioxide terms using their global warming potential, so a much smaller quantity of methane or nitrous…

This is the complement law for addition, which corresponds to the OR operation. Whatever value A takes, one of A and its complement must be 1, and an OR gate gives 1 whenever any input is 1, so the expression is 1 in both cases.

Each input can take one of two values, so for three inputs the number of distinct combinations is two multiplied by itself three times, that is two raised to the power three, which is eight.

It is the only gate that takes a single input, and it simply reverses the logic level it receives, giving 1 for an input of 0 and 0 for an input of 1; because the output is the inverse or complement of the input, the circuit is called an inverter.

Adding two single bits gives a sum that is 1 when exactly one of the bits is 1 and 0 when both are 0 or both are 1, which is precisely the XOR rule; so in a half adder the sum line comes from an XOR gate.

The system was a work of pure mathematics for decades until Claude Shannon showed that it described electrical switching circuits exactly, which opened the way to digital computing.

In Boolean algebra a literal is any single appearance of a variable in an expression, whether it appears plain or with a bar over it.

An exclusive OR gate is a difference detector: it gives 1 for the combinations 0 and 1 or 1 and 0, and gives 0 when the inputs agree.

De Morgan's second theorem states that NOT of A AND B equals NOT A OR NOT B. The working rule is to break the bar and change the sign, so a dot under a complement becomes a plus once the complement is distributed over the variables.

Each of these gates alone is enough to build every other gate and so every logic circuit: a NAND with its two inputs tied together acts as a NOT, two NANDs in sequence give an AND, and a suitable arrangement of three gives an OR, and the same can be…

Read the table row by row. The output is 0 only when both inputs are 0, and it is 1 in the other three rows, including the row where both inputs are 1.
