उत्तर : 2. "480 kms"
व्याख्या :
Answer: B) 480 kms Explanation: Now, the distance covered by Chennai express in 2 hrs = 60 x 2 = 120 kms Let the Charminar Express takes 't' hrs to catch Chennai express => 80 x t = 60 x (2 + t) => 80 t = 120 + 60t => t = 6 hrs Therefore, the distance away from Hyderabad the two trains meet = 80 x 6 = 480 kms.

उत्तर : 3. "Fructose"
व्याख्या :
Answer: C) Fructose Explanation: Fructose is an Organic molecule among the given options. Organic Molecules : An organic molecule is one which contains carbon, although not all compounds that contain carbon are organic molecules. Noticeable exceptions are carbon monoxide (CO), carbon dioxide (CO2), carbonates (e.g. calcium carbonate), carbides (e.g. calcium carbide) and cyanides (e.g. sodium cyanide). Pure carbon compounds such as diamond and graphite are also not organic compounds. Organic molecules can range in size from simple molecules to complex structures containing thousands of atoms. Although carbon is present in all organic compounds, other elements such as hydrogen (H), oxygen(O), nitrogen (N), sulfur (S) and phosphorus (P) are also common in these molecules. In simple, Molecules needed for life that have carbon are called Organic Molecules.

उत्तर : 1. "60"
व्याख्या :
Answer: A) 60 Explanation: Given letters are k, l, m, n, o = 5 number of letters to be in the words = 3 Total number of words that can be formed from these 5 letters taken 3 at a time without repetation of letters = 5P3 ways. ⇒ 5P3 = 5 x 4 x 3 = 60 words.

उत्तर : 2. "Glycolysis"
व्याख्या :
Answer: B) Glycolysis Explanation: Glycolysis is common between Aerobic and Anaerobic Respiration. Cellular respiration is the process by which glucose is broken down to form ATP molecules, which act as carriers of cellular energy. The first phase is called glycolysis and is common to both aerobic (respiration in the presence of oxygen) and anaerobic (respiration in the absence of oxygen) respiration. During glycolysis, glucose is split to forms two pyruvate molecules and 2 molecules of ATP. This occurs in the cytoplasm of the cell. If oxygen in present, the pyruvate molecules will be used in the Krebs cycle, to yield more ATP molecules. If oxygen is absent, the pyruvate is converted into lactic acid, or ethanol and carbon dioxide, in animals or plants, respectively.

उत्तर : 2. "Political power shifted to the bourgeoisie"
व्याख्या :
Answer: B) Political power shifted to the bourgeoisie Explanation: One of the most important result of the French Revolution was that Political power shifted to the bourgeoisie (Middle class people).

The bourgeoisie gained an enormous amount of political power when the National Assembly issued the Declaration of the Rights of Man, and drafted a new constitution for France.
