Cairn Reasoning Question

DIRECTIONS for the questions 1 to 5: Study the following information to answer the given question.
Eight friends, J, K, L, M, S, T, U and V are seated in a straight line, but not necessarily in the same order. Some are them are facing north while some face south.
  • K sits second from the end of the line. U sits third to the left of K.
  • T faces south. V sits fourth to the left of T. T is not an immediate neighbor of U. T does not sit at any of the extreme ends of the line.
  • Both the immediate neighbors of J face north. J does not sit at any of the extreme ends of the line.
  • J faces a direction opposite to that of V. (i.e. If V faces north then J faces south and vice-versa.)
  • L sits second to the left of J.
  • Immediate neighbors of K face opposite directions (i.e. if one neighbor faces north then the other faces south and vice-versa.)
  • Persons sitting at extreme ends face opposite directions (i.e. if one person faces north then the other person faces south and vice-versa.)
  • As many people sit between U and J as between U and S.
  • Immediate neighbors of U face same directions (i.e. if one neighbor faces north then the other also faces north and vice-versa).
  1. Which of the following is true based on the given arrangement?
    1. V sits at one of the extreme ends of the line,
    2. L faces north,
    3. None of the given options is true
    4. Only three people face north
    5. S and U face the same directions
    Answer: Option A
    M(n) K(s) T(s) S(s) U(n) J(s) V(n) L(s)
    n = north and s = south
    Only three people face north is true option on the given arrangement.
  2. Who amongst the following faces north?
    1. L
    2. M
    3. J
    4. K
    5. S
    Answer: Option B
    M(n) K(s) T(s) S(s) U(n) J(s) V(n) L(s)
    n = north and s = south
    From the options, M faces north.
  3. Who amongst the following sits third to the left of S?
    1. K
    2. J
    3. V
    4. L
    5. No one as less than three people sits to the left of S.
    Answer: Option C
    M(n) K(s) T(s) S(s) U(n) J(s) V(n) L(s)
    n = north and s = south
    V sits third to the left of S.
  4. How many people sit exactly between T and U?
    1. Four
    2. Three
    3. Two
    4. More than four
    5. One
    Answer: Option E
    M(n) K(s) T(s) S(s) U(n) J(s) V(n) L(s)
    n = north and s = south
    One people sit exactly between T and U.
  5. Who among the following represent the persons sitting at extreme ends of the line?
    1. M, V
    2. M, S
    3. L, V
    4. M, L
    5. S, V
    Answer: Option D
    M(n) K(s) T(s) S(s) U(n) J(s) V(n) L(s)
    n = north and s = south
    M, L represent the persons sitting at extreme ends of the line.
DIRECTIONS for question 6 to 8: Refer to the bar graph and answer the given question.
Big Bull
  1. What is the difference between average number of students enrolled in institute A in 2009 and 2010 and that in institute B in 2011 and 2012?
    1. 20
    2. 40
    3. 30
    4. 10
    5. 60
    Answer: Option B
    A = 440/2 = 220 and B = 360/2 = 180
    Difference = 220 – 180 = 40
  2. If the number of enrolled students in institute A in 2013 is 25% less than that in 2014, how many students were enrolled in institute A in 2014?
    1. 450
    2. 480
    3. 440
    4. 500
    5. 490
    Answer: Option C
    Let students enrolled in 2014 In institute A be ‘x’ 85% of x = 330 ⇒ x = 440
  3. In 2009, 65% of students enrolled in institute B were male. If the respective ratio between number of male students enrolled in institutes A and B in 2009 was 3: 4, what was the number of male students enrolled in institute A in the same year?
    1. 111
    2. 117
    3. 123
    4. 114
    5. 105
    Answer: Option B
    Male students of B = 65% * 240 =156
    Total students male = 4/7 x = 156 ⇒ x = 273
    Male students of A = 273 -156= 117
DIRECTIONS for questions 9 to 10: Read the following information and answer the given question:
Vansh starts walking from Point E and walks 25m towards the north. He then takes a right turn and walks for 15m. He makes a left turn and stops at Point M after walking for 20m.
Point K is 30m to the west of Point M. Point K is 45m to the north of Point J. Point J is 10m to the east of Point L.
  1. How far and in which direction is Point E with respect to Point L?
    1. 30m towards West
    2. 25m towards East
    3. 20m towards East
    4. 20m towards West
    5. 25m towards West
    Answer: Option B
    Big Bull
    So Point E w.r.t Point L, 15+10= 25m due East
  2. If Neha is standing at Point D which is 20m to the north of Point L, in which direction will she have to walk in order to reach Point M?

    4. North-east
    5. North
    Answer: Option C
