Sr. No	Logical Reasoning
1.	Number Series
	1	Look at this series: 2, 1, (1/2), (1/4), ... What number should come next?
		A.    (1/3)	B.    (1/8)	C.     (2/8)	D.   (1/16)
		Answer: Option B Explanation: This is a simple division series; each number is one-half of the previous number. In other terms to say, the number is divided by 2 successively to get the next result. 4/2 = 2 2/2 = 1 1/2 = 1/2 (1/2)/2 = 1/4 (1/4)/2 = 1/8 and so on.
	2	Look at this series: 7, 10, 8, 11, 9, 12, ... What number should come next?
		A.    7	B.    10	C.     12	D.   13
		Answer: Option B Explanation: This is a simple alternating addition and subtraction series. In the first pattern, 3 is added; in the second, 2 is subtracted.
	3	Look at this series: 36, 34, 30, 28, 24, ... What number should come next?
		A.    20	B.    22	C.     23	D.   26
		Answer: Option B Explanation: This is an alternating number subtraction series. First, 2 is subtracted, then 4, then 2, and so on.
	4	Look at this series: 22, 21, 23, 22, 24, 23, ... What number should come next?
		A.    22	B.    24	C.     25	D.   26
		Answer: Option C Explanation: In this simple alternating subtraction and addition series; 1 is subtracted, then 2 is added, and so on.
	5	Look at this series: 53, 53, 40, 40, 27, 27, ... What number should come next?
		A.    12	B.    14	C.     27	D.   53
		Answer: Option B Explanation: In this series, each number is repeated, then 13 is subtracted to arrive at the next number.
	6	Look at this series: 21, 9, 21, 11, 21, 13, 21, ... What number should come next?
		A.    14	B.    15	C.     21	D.   23
		Answer: Option B Explanation: In this alternating repetition series, the random number 21 is interpolated every other number into an otherwise simple addition series that increases by 2, beginning with the number 9.
	7	Look at this series: 58, 52, 46, 40, 34, ... What number should come next?
		A.    26	B.    28	C.    30	D.   32
		Answer: Option B Explanation: This is a simple subtraction series. Each number is 6 less than the previous number
