Answer: D) 41 Explanation: We can get this by any of two explanations.   Answer 1: 41 7 = 3 + 4  = 34 Similarly, 5 = 4 + 1  = 41   Answer 2 :  41 7 - 3 = 4  => 34 Similarly, 5 - 4 = 1  => 41

Answer: A) 36 Explanation:   LCD is nothing but Lowest or Least Common Denominator   Here LCD of 12 and 18 means LCD of two fractions with denominators 12 and 18 respectively.   Therefore, LCM of 12 & 18 = 6 x 3 x 2 = 36     How to calculate LCD :: The lowest common denominator or least common denominator (LCD) is the least common multiple (LCM) of the denominators of a set of fractions.

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: A) 12 Explanation: We have 12 months.   In every month we get 28 or more days.    So that implies we get 28 days in each and every month.

Answer: D) All the above Explanation: The Multiples of 18 are 18, 36, 54, 72, 90, 108, 126, ....   Multiples of 18 are nothing but numbers which are divisible by 18 leaving remainder 0.   An infinite number of multiples of 18 can be achieved by adding 18 to each subsequent multiple.

Answer: D) Joel Explanation: If we consider the given numbers  6, 4, 9, 10, 11 to be the month number then we can easily find the killer. 6 – June – J 4 – April – A 9 – September – S 10 – October – O 11 – November – N Hence the answer is JOEL.
