Practice Reasoning Questions For Upcoming Exams (Data Sufficiency) Set- 98:
Dear Readers, Important Practice Reasoning Questions with explanation for Upcoming Exams was given here with explanation, candidates those who are preparing for Banking and all other Competitive exams can use this practice questions.
Directions (Q. 1-5): Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements arc sufficient to answer the question. Read both the statements and give answer
a) if the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.
b) if the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.
c) if the data either in statement I alone or in statement II alone are sufficient to answer the question.
d) if the data in both statement I and II together are not sufficient to answer the question.
e) if the data in both statement I and II together are necessary to answer the question.
1).Is C the son of S?
I.S is father of F. F is the only sister of B. B is married to K. K, the only child of L, is the sister-in-law of C.
II.F is sister of C. F is daughter of T. T is mother of B. B is son of S. S has only one daughter.
2).How many people are sitting in a circle, where all the people are facing the centre?
I.B sits third to the right of M. Only one person sits between B and P. P sits third to the left of Q. P is an immediate neighbour of V.
II.P sits second to the left of M. V is an immediate neighbour of P. V sits second to the right of S. Only one person sits between S and M.
3).Ten people are sitting in two parallel rows seating rive people each, in such a way that there is an equal distance between adjacent persons. In row- I , J, K, L, M and N are seated and all of them are facing, south. In row-2, D, E, F, G and H are seated and all of them are facing north (therefore, in the given seating arrangement each member seated in a row faces another member of the other row) Who amongst D, E, F, G and H faces L?
I.M sits third to the left of K. The one who faces M sits on the immediate right of F. L is an immediate neighbour of J. D sits second to the right of G. G does not sit at an extreme end of the line.
II.N sits at an extreme end of the line. Only two people sit between N and J. The one who faces J sits on the immediate left of F. E sits second to the left of F. Only one person sits between L and K.
4).Among six people A, B, C, D, E and F, each having a different number of experiences, viz 4 9,13,15, 22 and 27 years (but not necessarily in the same order), who is the person with the second lowest experience?
I.Only-two people are more experienced than B. F is less experienced than B but more experienced than A. Both E and C are more experienced than D. D's experience is an even number
II.C is more experienced than F but less than E. Both A and D are less experienced than F. B is more experienced than D. B's experience is in odd number.
5).Point R is in which direction with respect to Point T?
I. Point M is 20m to the south of Point T. Point T is 15m to the east of point L. Point L is 40m to the north of Point X. Point X is exactly between Points R and C such that points R, X and C form, a straight line of 30m.
II.Point R is 30m to the north of Point J. Point J is 15m to the west of Point S. Point S is 30m to the north of Point U. Point U is 10m to the west of Point M. Point T is to the north of Point M.
Directions (Q. 6-9): In each of the following questions two rows of number are given. The resultant number in each row is to be worked out separately based on the following rules and the question below the rows to be answered. Rules:
(i) If an odd number is followed by a composite odd number, they are to be multiplied. (ii) If an even number is followed by an odd number, they are to be added.
(iii) If an even number is followed by a number which is a perfect square, the even number is to be subtracted from the perfect square.
(iv) If an odd number is followed by an even number, the second one is to be subtracted from the first one.
(v) If an odd number is followed by a prime odd number, the first number is to be divided by the second number.
(vi) If an even number is followed by an even number the first number is divided by the second number.
Note: Rule (iii) gets priority over Rule (ii) and (vi).
6). I.38 39 7
II.49 42 15
Which of the following will be the answer if the resultants of the two rows are added?
a) 116
b) 102
c) 118
d) 105
e) 107
7). I.28 49 3
II.x 8 25
If x is the resultant of the first row, what will be the resultant of the second row?
a) 75
b) 90
c) 200
d) 100
e) None of these
8). I.15 25 3
II. 3 102 x
If x is the resultant of the first row, what will be the answer, if the resultants of the two rows are multiplied?
a) -24875
b) 18975
c) 19875
d) -21795
e) None of the above
9). I. 18 64 23
II. 78 x 3
If x is the resultant of the first row, what will be the resultant of the second row?
a) 45
b) 54
c) 69
d) 46
e) Other than the given options
Explanation:
Thus I is sufficient to answer the question.
Hence C is son of S.
Thus II alone is sufficient to answer the question.
2). D)From I.
Thus there are either five or six persons.
Thus there are either five or seven persons. From I and II. the two can’t be combined.
3). E)We are taking only two possible cases
hence I is not sufficient to answer the question.
From II. We are taking only two possible cases.
From I (i) and II (i):
Thus, both are necessary to answer the given question. hence F faces L.
4). A)From I. E/C > C/E > B > F > A > D
(ii) E > C > F > A > B(9) > D
Hence II alone is not sufficient to answer the question.
5). D).From I.
Point R is either towards south or southwest from Point T.
Thus, I alone is not sufficient.
From II.
Hence II alone is not sufficient to answer the question. Thus, point R is either towards northwest, southwest or west of point T.
6). A) Applying rule (ii) and (v), we get
I.(38 + 39) ÷ 7 = 77 ÷ 7 = 11
II. Apply rule (iv)
(49 — 42) 15
7 15
7×15 = 105 (use rule (1))
Sum of the resultants of both rows = 11 + 105 = 116
7). E)
I.28 49 3
(49 — 28) 3 (use rule (iii))
= 21 3
= 21 ÷ 3 (Use rule (v))
II.7 8 25
(7 — 8) 25 (Use rule (iv))
= -1 25
= -1 x 25 (Use rule(i))
I.15 25 3
= 15 x 25 3(use rule (i))
375 3
= 375 ÷ 3 use rule (v))
II.3 102 x
3 102 125
(3— 102) 25 (use rule v))
=-99 25
= -99 x 25 (Use rule (i))
Resultant product = 125 x —2475
I.18 64 23
= (64.— 18) 23 (use rule (iii))
46 23
= 46 + 23 (Use rule (ii))
II.78 x 3
=78 69 3
(78 + 69) 3 (Use rule (ii))
147 3
= 147 ÷ 3 (Use rule (v))
