Coins in sacks in a 3×3 array of boxes

There are nine boxes arranged in a 3×3 array as shown in Tables 1 and 2. Each box contains three sacks. Each sack has a certain number of coins, between 1 and 9, both inclusive.

The average number of coins per sack in the boxes are all distinct integers. The total number of coins in each row is the same. The total number of coins in each column is also the same.

Data for this set (chart, table or figure)

Table 1 gives information regarding the median of the numbers of coins in the three sacks in a box for some of the boxes. In Table 2 each box has a number which represents the number of sacks in that box having more than 5 coins. That number is followed by a * if the sacks in that box satisfy exactly one among the following three conditions, and it is followed by ** if two or more of these conditions are satisfied.

i) The minimum among the numbers of coins in the three sacks in the box is 1.

ii) The median of the numbers of coins in the three sacks is 1.

iii) The maximum among the numbers of coins in the three sacks in the box is 9.

Set solution: how to crack this set

The nine box averages are distinct integers from 1 to 9 (sum 45). Rows have equal totals and columns have equal totals, so each row and column of averages sums to 15 and each row holds 45 coins.

Average 1 is three 1-coin sacks ("0**"): R3C3. Average 9 is three 9s ("3*", median not 8): R2C3. Then R1C3 $= 5$ .

R3C1 (median 8, "3*") must be $\{7, 8, 9\}$ , average 8, so R3C2 $= 6$ .

The remaining averages 2, 3, 4, 7 fit only as R1: 3, 7; R2: 4, 2.

Box	Avg	Sacks
R1C1	3	1, 1, 7
R1C2	7	3, 9, 9
R1C3	5	1, 6, 8
R2C1	4	1, 2, 9
R2C2	2	1, 2, 3
R2C3	9	9, 9, 9
R3C1	8	7, 8, 9
R3C2	6	1, 8, 9
R3C3	1	1, 1, 1

Fund raising by five firms over the years

Odsville has five firms - Alfloo, Bzygoo, Czechy, Drjbna and Elavalaki. Each of these firms was founded in some year and also closed down a few years later.

Each firm raised Rs. 1 crore in its first and last year of existence. The amount each firm raised every year increased until it reached a maximum, and then decreased until the firm closed down. No firm raised the same amount of money in two consecutive years. Each annual increase and decrease was either by Rs. 1 crore or by Rs. 2 crores. The table below provides partial information about the five firms.

Set solution: how to crack this set

Each sequence starts and ends at 1, rises then falls, in steps of 1 or 2.

Drjbna (2011–15, total 10): only 1, 2, 4, 2, 1. Czechy (total 9, from 2013): only 1, 2, 3, 2, 1.

Bzygoo (2012–15): 1, 2, 3, 1 or 1, 3, 2, 1.

Alfloo (2009–16, total 21): 1, 2, 3, 4, 5, 3, 2, 1 or 1, 2, 3, 5, 4, 3, 2, 1.

Elavalaki (from 2010, total 13): 1, 2, 3, 4, 2, 1 or 1, 2, 4, 3, 2, 1 or 1, 3, 5, 3, 1.

Random draw scores and daily ranks

Three participants - Akhil, Bimal and Chatur participate in a random draw competition for five days. Every day, each participant randomly picks up a ball numbered between 1 and 9. The number on the ball determines his score on that day. The total score of a participant is the sum of his scores attained in the five days. The total score of a day is the sum of participants’ scores on that day. The 2-day average on a day, except on Day 1, is the average of the total scores of that day and of the previous day. For example, if the total scores of Day 1 and Day 2 are 25 and 20, then the 2-day average on Day 2 is calculated as 22.5. Table 1 gives the 2-day averages for Days 2 through 5.

Participants are ranked each day, with the person having the maximum score being awarded the minimum rank (1) on that day. If there is a tie, all participants with the tied score are awarded the best available rank. For example, if on a day Akhil, Bimal, and Chatur score 8, 7 and 7 respectively, then their ranks will be 1, 2 and 2 respectively on that day. These ranks are given in Table 2.

The following information is also known.

1. Chatur always scores in multiples of 3. His score on Day 2 is the unique highest score in the competition. His minimum score is observed only on Day 1, and it matches Akhil’s score on Day 4.

2. The total score on Day 3 is the same as the total score on Day 4.

3. Bimal’s scores are the same on Day 1 and Day 3.

Set solution: how to crack this set

From the 2-day averages and Day 3 $=$ Day 4: day totals are 15, 15, 16, 16, 18.

Chatur: Day 2 = 9 (unique highest). His minimum (only on Day 1) must be 3, and his other days are 6. Akhil's Day 4 $= 3$ .

Day 3: Akhil $=$ Bimal $= 5$ (total 16). Day 4: Bimal $= 16 - 3 - 6 = 7$ . Bimal's Day 1 $=$ Day 3 $= 5$ , so Akhil's Day 1 $= 7$ .

Day 2: Akhil + Bimal $= 6$ with Akhil higher: (5, 1) or (4, 2). Day 5: Akhil + Bimal $= 12$ , Bimal above 6, no 9: (5, 7) or (4, 8).

Totals: Chatur 30; Akhil $= 15 + A_2 + A_5$ ; Bimal $= 17 + B_2 + B_5$ .

Visitors on four rides in a park

Anjali, Bipasha, and Chitra visited an entertainment park that has four rides. Each ride lasts one hour and can accommodate one visitor at one point. All rides begin at 9 am and must be completed by 5 pm except for Ride-3, for which the last ride has to be completed by 1 pm. Ride gates open every 30 minutes, e.g. 10 am, 10:30 am, and so on. Whenever a ride gate opens, and there is no visitor inside, the first visitor waiting in the queue buys the ticket just before taking the ride. The ticket prices are Rs. 20, Rs. 50, Rs. 30 and Rs. 40 for Rides 1 to 4, respectively. Each of the three visitors took at least one ride and did not necessarily take all rides. None of them took the same ride more than once. The movement time from one ride to another is negligible, and a visitor leaves the ride immediately after the completion of the ride. No one takes a break inside the park unless mentioned explicitly.

The following information is also known.

1. Chitra never waited in the queue and completed her visit by 11 am after spending Rs. 50 to pay for the ticket(s).

2. Anjali took Ride-1 at 11 am after waiting for 30 mins for Chitra to complete it. It was the only ride where Anjali waited.

3. Bipasha began her first of three rides at 11:30 am. All three visitors incurred the same amount of ticket expense by 12:15 pm.

4. The last ride taken by Anjali and Bipasha was the same, where Bipasha waited 30 mins for Anjali to complete her ride. Before standing in the queue for that ride, Bipasha took a 1-hour coffee break after completing her previous ride.

Set solution: how to crack this set

Chitra spent 50 without waiting and was done by 11: Ride-3 (9–10) and Ride-1 (10–11), since Anjali waited for her on Ride-1 till 11.

By 12:15 everyone spent 50. Anjali: Ride-1 (20) at 11, then Ride-3 (30) at 12–1 (Ride-3 must end by 1 pm).

Bipasha starts at 11:30 and has spent 50 by 12:15: Ride-2 (11:30–12:30).

Bipasha: second ride 12:30–1:30, coffee 1:30–2:30, queue at 2:30 and waits till 3:00 for Anjali. So Anjali's last ride is 2:00–3:00, after a ride from 1:00–2:00.

Bipasha's last ride can't be Ride-2 again, so it's Ride-4; Anjali: Ride-2 (1–2), Ride-4 (2–3). Bipasha's second ride is Ride-1 (12:30–1:30).

Anjali: R1, R3, R2, R4. Bipasha: R2, R1, R4. Chitra: R3, R1.
