Answer: A) 14/33 Explanation: Total number of chairs = (3 + 5 + 4) = 12. Let S be the sample space. Then, n(s)= Number of ways of picking 2 chairs out of 12 = 12×11/2×1 = 66 Let n(E) = number of events of selecting 2 chairs for selecting no white chairs. => 8C2 = 8×7/2×1 = 28 Therefore required probability = 28/66 = 14/33.

Answer: C) England Explanation: We fought against England in the Revolutionary War for Independence from the British rule.

Answer: A) 36 & 90 Explanation: the next 2 number in series we need to divide the series into 2 different series First series : 4 , 6, 12, 30 ?? Second Series : 12,18,26, ?? So we need to see for the pattern for those series in order to find the next two number , we can do this by finding the difference or division , multiplication logic whatever may apply :   Pattern of Series 1 :   6 divide 4 : 1.5 Next number i.e 12 divided by 6=2 Next number i.e 30 divided by 12 =2.5 So series is going in multiples of 1.5, 2, 2.5, 3 , so on So first series will look like 4 , 6, 12, 30, 30x3 =90   Pattern of Series 2 : 12,18,26, ??   Its simple Adding numbers with iterative logic (i.e 6, 8, then followed by 10, 12) Series will be like 12,18,26,36.   For the next two numbers : Series will be like 4, 12, 6, 18, 12, 26, 30, 36, 90

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.

Answer: B) 26 Explanation: Let the integer be x. Then,  x2-20x = 156   (x + 6)(x - 26) = 0   x = 26   The integer is 26.

Answer: A) promise to pay for goods later. Explanation: If as a business, you buy goods or services on credit from a supplier (accounts payable) then the supplier will supply the goods and business will incur a liability to the supplier for that amount, but no cash will change hands at that stage. Some of those shop keepers allowed regular "trustworthy" customers to purchase items without having the full payment. Hence, Buying on credit means that no actual money has changed hands.

Answer: B) 8 Explanation: The easiest way would measure it through half a liter water bottle. There are approximately 16.9 ounces(oz) of water in a 500ml water bottle.   Gallon is an imperial customary volume unit for the U.S.   As we have previously mentioned, the 16.9oz bottle is also known as 500ml in the metric system. According to U.S. standard, 1 gallon stands for 128 fluid oz.   Hence, Number of bottles in 1 gallon = 128/16.9 = 7.57 =~ 8.
