Answer: D) 64 Explanation: The logic in the challenge is  81x6 = 9x6 = 54 144x7=84     Similarly, 64x8 = 8x8 = 64.

Answer: B) 166 2/3 million Explanation: 5% - 2% = 3%=> 3% ------ 5 million bags 100% ---- ? => 166 2/3 million bags.

Answer: D) Both a and b sufficient Explanation: Let the sum be Rs. x a. gives, S.I = Rs. 9000 and time = 9 years. b. gives, Sum + S.I for 6 years = 2 x Sum --> Sum = S.I for 6 years. Now, S.I for 9 years = Rs. 9000 S.I for 1 year = Rs. 9000/9 = Rs. 1000. S.I for 6 years = Rs. (1000 x 6)= Rs. 6000. --> x = Rs. 6000 Thus, both a and b are necessary to answer the question.

Answer: D) Cytoplasm Explanation: Translation occurs in the cytoplasm whereas transcription occurs in the nucleus.   Transcription and Translation: Terms transcription and translation in biology are generally related to the DNA and its properties. Human cells replicate. In order to do that, they have to produce the same constituents for the new cell that is to be made. The only way to do that is by producing proteins.   The proteins are produced in the process that is called protein synthesis. The first step is in the nucleus where a particular gene is being expressed so it enables all protein factors to come and to replicate that part of a chromosome. This is finished when mRNA, the same single-stranded genetic code of a particular gene, is formed. This is transcription. Right after that, the mRNA enters the cytoplasm through nuclear pores. There, it could be translated into proteins by ribosomes. This process is called translation.

Answer: A) L Explanation: The Logic followed in the given puzzle is : L x P = 12 x 16 = 192 (Alphabetical numbers of L & P) P x T = 16 x 20 = 320 (Alphabetical numbers of P & T) Similarly, K x () = 132 => () = 132/11 = 12 => L Hence, the missing letter is L

Answer: D) 162 sec Explanation: Given two trains of length = 180 mts + 180 mts  The distance is = Length of trains = 360 mts  Speed = 58 - 50 = 8 kmph x 5/18 m/s Then, Time = dis/speed = (360x18) / (8x5) = 162 sec.

Answer: B) Any one pair of A and B, B and C or C and A is sufficient Explanation: From the given data, Let the two gits of a number be x & y A) x + y = 15   B) x2 - y2 = 45 (x+y) (x - y) = 45   C) x - y = 3 From any 2 of the given 3 statements, we can find that 2 digit number as  2x = 18 => x = 9 => y = 6 Hence, 2 digit number is 96.   Any one pair of A and B, B and C or C and A is sufficient to find.

Answer: A) homogeneous Explanation: A Mixture is a material made up of two or more different substances which are mixed.   Mixtures can be either homogeneous or heterogeneous.   * A homogeneous mixture is a type of mixture in which the composition is uniform and every part of the solution has the same properties. * A heterogeneous mixture is a type of mixture in which the components can be seen, as there are two or more phases present.   Air is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances.
