Puzzle
Directions (1 - 3): (i) There is a group of five girls. (ii) Kamini is second in height but younger than Rupa. (iii) Pooja is taller than Monika but younger in age. (iv) Rupa and Monika are of the same age but Rupa is tallest between them. (v) Neelam is taller than Pooja and elder Rupa.
1. If they are arranged in the ascending order of height, who will be in third position?
    A. Monika B. Rupa C. Monika or Rupa D. Data inadequate E. None of these

Answer: Option (E)
Explanation: We first find the sequence of height : By (iii), we have: M < P. By (v), we have : P < N. Now, Rupa is tallest and Kamini is second in height. So, the sequence of heights is : M < P < N < K < R. Now, we determine the age sequence : By (ii), we have K < R. By (iii), we have: P < M. By (iv), we have : R = M. By (v), we have : R < N. So, the sequence of ages is : N < R = M < K < P or N < R = M < P < K. Clearly, in the increasing order of height, Neelam is in the third position. Hence, the answer is (E).
2. If they are arranged in the descending order of their ages, who will be in the fourth position?
    A. Monika or Rupa B. Kamini C. Monika D. Data inadequate E. None of these

Answer: Option (E)
Explanation: We first find the sequence of height : By (iii), we have: M < P. By (v), we have : P < N. Now, Rupa is tallest and Kamini is second in height. So, the sequence of heights is : M < P < N < K < R. Now, we determine the age sequence : By (ii), we have: K < R. By (iii), we have : P < M. By (iv), we have : R = M. By (v), we have : R < N. So, the sequence of ages is : N < R = M < K < P or N < R = M < P < K. Clearly, in the decreasing order of ages, Neelam will be in the fourth position (because Monika and Rupa both lie at third position). Hence, the answer is (E).
3. To answer the question "who is the youngest person in the group", which of the given statements is superfluous?
    A. Only (i) B. Only (ii) C. Only (v) D. Either (i) or (iv) E. None of these

Answer: Option (A)
Explanation: We first find the sequence of height : By (iii), we have: M < P. By (v), we have : P < N. Now, Rupa is tallest and Kamini is second in height. So, the sequence of heights is : M < P < N < K < R. Now, we determine the age sequence : By (ii), we have K < R. By (iii), we have : P < M. By (iv), we have : R = M. By (v), we have : R < N. So, the sequence of ages is : N < R = M < K < P or N < R = M < P < K. Clearly, only statement (i) is not necessary. Hence, the answer is (A).
Direction (4 - 5): Six plays -- A, B, C, D, E, and F are to be staged, one on each day from Monday to Saturday. The schedule of the plays is to be in accordance with the following: (i) A must be staged a day before E. (ii) C must not be staged on Tuesday. (iii) B must be staged on the day following the day on which F is staged. (iv) D must be staged on Friday only and should not be immediately preceded by B. (v) E must not be staged on the last day of the schedule.
4. Which of the following plays immediately follows B?
    A. A B. C C. D D. E E. F

Answer: Option (A)
Explanation: Clearly, D must be staged on Friday. A must be staged before E i.e., order AE must be followed. But E cannot be staged on last day. Also, B must be staged immediately after F i.e., order FB must be followed. But B cannot precede D. So, F and B can be staged on Monday and Tuesday and A and E on Wednesday and Thursday. C, which cannot be staged on Tuesday shall be staged on Saturday. Thus, the order followed will be:
Monday Tuesday Wednesday Thursday Friday Saturday
F B A E D C
Clearly, A immediately follows B. So, the answer is (A).
5. Which of the following plays in on Monday?
    A. E B. F C. C D. B E. A

Answer: Option (B)
Explanation: Clearly, D must be staged on Friday. A must be staged before E i.e., order AE must be followed. But E cannot be staged on last day. Also, B must be staged immediately after F i.e., order FB must be followed. But B cannot precede D. So, F and B can be staged on Monday and Tuesday and A and E on Wednesday and Thursday. C, which cannot be staged on Tuesday shall be staged on Saturday. Thus, the order followed will be:
Monday Tuesday Wednesday Thursday Friday Saturday
F B A E D C
F will be played on Monday. So, the answer is (B).

    A. I alone is sufficient while II alone is not sufficient B. II alone is sufficient while I alone is not sufficient C. Either I or II is sufficient D. Neither I nor II is sufficient E. Both I and II are sufficient

Answer: Option (E)
Explanation: From both I and II, we find that Rahul is (35 - 25) = 10 years older than his brother, who was born in 1964. So, Rahul was born in 1954.
2. How many children are there in the row of children facing North? Statements: I. Vishakha who is fifth from the left end is eighth to the left of Ashish who is twelfth from the right end. II. Rohit is fifth to the left of Nisha who is seventh from the right end and eighteenth from the left end.
    A. I alone is sufficient while II alone is not sufficient B. II alone is sufficient while I alone is not sufficient C. Either I or II is sufficient D. Neither I nor II is sufficient E. Both I and II are sufficient

Answer: Option (C)
Explanation: Since 8th to the left of 12th from the right is 20th from the right, so from I, we know that Vishakha is 5th from left and 20th from right i.e. there are 4 children to the left and 19 to the right of Vishakha. So, there are (4 + 1 + 19) i.e. 24 children in the row. From II, Nisha is 7th from right and 18th from the left end of the row. So, there are (6 + 1 + 17) = 24 children in the row.

B is heavier than T and C and is less heavier than V who is not the heaviest. II. C is heavier than only T. A. I alone is sufficient while II alone is not sufficient B. II alone is sufficient while I alone is not sufficient C. Either I or II is sufficient D. Neither I nor II is sufficient E. Both I and II are sufficient
Answer: Option (A)
Explanation: From I, we have B > T, B > C, V > B. Thus, V is heavier than each one of B, T, and C. But V is not the heaviest. So, E is the heaviest. Thus, we have the order. E>V>B>T>C or E>V>B>C>T. Clearly, B is third from the top.

Interpretation of Graphs etc.
Directions (1 -5): The bar graph given below shows the foreign exchange reserves of a country (in million US $) from 1991 - 1992 to 1998 - 1999.

1. The ratio of the number of years, in which the foreign exchange reserves are above the average reserves, to those in which the reserves are below the average reserves is?
    A. 2:6 B. 3:4 C. 3:5 D. 4:4

Answer: Option (C)
Explanation: Average foreign exchange reserves over the given period = 3480 million US $. The country had reserves above 3480 million US $ during the years 1992-93, 1996-97 and 1997-98, i.e., for 3 years and below 3480 million US $ during the years 1991-92, 1993-94, 1994-95, 1995-56 and 1998-99 i.e., for 5 years. Hence, required ratio = 3 : 5.
2. The foreign exchange reserves in 1997-98 were how many times that in 1994-95?
    A. 0.7 B. 1.2 C. 1.4 D. 1.5

Answer: Option (D)
Explanation: Required ratio = [latex]\frac{5040}{3360}[/latex] = 1.5.
3. For which year, the percent increase of foreign exchange reserves over the previous year, is the highest?
    A. 1992-93 B. 1993-94 C. 1994-95 D. 1996-97

Answer: Option (A)
Explanation: There is an increase in foreign exchange reserves during the years 1992 - 1993, 1994 - 1995, 1996 - 1997, 1997 - 1998 as compared to the previous year (as shown by bar-graph). The percentage increase in reserves during these years compared to the previous year are: For 1992 - 1993 = [[latex]\frac{(3720 - 2640)}{2640}[/latex] x 100]% = 40.91%. For 1994 - 1995 = [[latex]\frac{(3360 - 2520)}{2520}[/latex] x 100]% = 33.33%. For 1996 - 1997 = [[latex]\frac{(4320 - 3120)}{3120}[/latex] x 100 ]% = 38.46%. For 1997 - 1998 = [[latex]\frac{(5040 - 4320)}{4320}[/latex]x 100 ]% = 16.67%. Clearly, the percentage increase over the previous year is highest for 1992 - 1993.
4. The foreign exchange reserves in 1996-97 were approximately what percent of the average foreign exchange reserves over the period under review?
    A. 95% B. 110% C. 115% D. 125%

Answer: Option (D)
Explanation: Average foreign exchange reserves over the given period =[[latex]\frac {1}{8}[/latex]x (2640 + 3720 + 2520 + 3360 + 3120 + 4320 + 5040 + 3120)]million US $ = 3480 million US $. Foreign exchange reserves in 1996 - 1997 = 4320 million US $. Therefore Required percentage = ([latex]\frac{4320}{3480}[/latex]x 100)% = 124.14% = 125%.
5. What was the percentage increase in the foreign exchange reserves in 1997-98 over 1993-94?
    A. 100 B. 150 C. 200 D. 620

Answer: Option (A)
Explanation: Foreign exchange reserves in 1997 - 1998 = 5040 million US $. Foreign exchange reserves in 1993 - 1994 = 2520 million US $. Therefore Increase = (5040 - 2520) = 2520 US $. Therefore Percentage Increase = ([latex]\frac{2520}{2520}[/latex] x 100)% = 100%.
