SSC CGL 2021 Previous Year GK Questions with Answers

The correct answer is A, Roman. The rupee sign blends the Devanagari letter "र" (Ra) with the Roman capital "R" with its vertical stem removed, so that it reads as an Indian letter and an international one at the same time. It was designed by D. Udaya Kumar, then a student at IIT Bombay and later a professor at IIT Guwahati, who won a nationwide open competition; the Union Cabinet approved it on 15 July 2010. The two parallel horizontal lines across the top stand for the tricolour and for the equality sign, a nod to a balanced economy. With this sign the rupee joined the dollar, pound, euro and yen as currencies with their own symbol. B, Ol Chiki, is the script created for the Santali language and has no part in the design. C, Brahmi, is the ancient script of Ashoka's edicts, not used here. D, Cyrillic, is the script of Russian and other Slavic languages. Exam tip: rupee symbol = Devanagari Ra + Roman R, designed by Udaya Kumar, adopted 15 July 2010.

The correct answer is B, Vitamin C. Vitamins fall into two groups: the water-soluble ones, which are vitamin C and the whole B-complex, and the fat-soluble ones, A, D, E and K. Vitamin C is ascorbic acid, found in citrus fruits, amla, guava and tomatoes; its deficiency causes scurvy, with bleeding gums and slow healing of wounds. Because water-soluble vitamins are not stored in the body and the extra is passed out in urine, they must be taken daily, while fat-soluble vitamins are stored in the liver and fatty tissue. A, Vitamin K, is fat-soluble and needed for blood clotting. C, Vitamin A, retinol, is fat-soluble and its deficiency causes night blindness. D, Vitamin D, calciferol, is fat-soluble, made in the skin in sunlight, and its lack causes rickets. Exam tip: remember "ADEK are fat-soluble"; everything else, B-complex and C, dissolves in water.

The correct answer is B, Article 279A. It empowers the President to constitute the Goods and Services Tax Council, a joint forum of the Centre and the States. The Article was inserted by the Constitution (One Hundred and First Amendment) Act, 2016, the same amendment that brought GST, and the Council was set up in September 2016. The Union Finance Minister is its Chairperson, the Union Minister of State for Finance and the finance or taxation ministers of all States are its members, and decisions need a three-fourths weighted majority in which the Centre holds one-third of the votes and the States together two-thirds. A, Article 246A, gives Parliament and the State legislatures the power to make laws on GST. C, Article 269A, deals with the levy and collection of GST on inter-State trade, that is, IGST. D, Article 323A, provides for administrative tribunals and has nothing to do with tax. Exam tip: 246A power to tax, 269A inter-State GST, 279A GST Council; all three came with the 101st Amendment.
