Question Numbers (11 to 15): Adhara, Bithi, Chhaya, Dhanavi, Esther, and Fathima are the interviewers in a process that awards funding for new initiatives. Every interviewer individually interviews each of the candidates individually and awards a token only if she recommends funding. A token has a face value of 2, 3, 5, 7, 11, or 13. Each interviewer awards tokens of a single face value only.

Once all six interviews are over for a candidate, the candidate receives a funding that is Rs.1000 times the product of the face values of all the tokens. For example, if a candidate has tokens with face values 2, 5, and 7, then they get a funding of Rs.1000 × (2 × 5 × 7) = Rs.70,000.

Pragnyaa, Qahira, Rasheeda, Smera, and Tantra were five candidates who received funding. The funds they received, in descending order, were Rs.390,000, Rs.210,000, Rs.165,000, Rs.77,000, and Rs.66,000. The following additional facts are known:

1. Fathima awarded tokens to everyone except Qahira, while Adhara awarded tokens to no one except Pragnyaa.

2. Rashida received the highest number of tokens that anyone received, but she did not receive one from Esther.

Question Numbers (16 to 20):


Given above is the schematic map of the metro lines in a city with rectangles denoting terminal stations (e.g. A), diamonds denoting junction stations (e.g. R) and small filled-up circles denoting other stations. Each train runs either in east-west or north-south direction, but not both. All trains stop for 2 minutes at each of the junction stations on the way and for 1 minute at each of the other stations. It takes 2 minutes to reach the next station for trains going in east-west direction and 3 minutes to reach the next station for trains going in north-south direction. From each terminal station, the first train starts at 6 am; the last trains leave the terminal stations at midnight. Otherwise, during the service hours, there are metro service every 15 minutes in the north-south lines and every 10 minutes in the east-west lines. A train must rest for at least 15 minutes after completing a trip at the terminal station, before it can undertake the next trip in the reverse direction. (All questions are related to this metro service only. Assume that if someone reaches a station exactly at the time a train is supposed to leave, (s)he can catch that train.)

Q. 16 If Hari is ready to board a train at 8:05 am from station M, then when is the earliest that he can reach station N?

Correct Answer

3

Explanation



Given that Hari is ready to board a train at 8:05 am from station M.
Trains leave after every 10 minutes. So Hari can catch the 8:10 train from M.
There are 17 stations, 2 junctions and 20 intervals, so time taken to travel = 20 × 2 + 17 × 1 + 2 × 2 = 61 minutes
Hence, time at which Hari reaches station N = 8:10 + 1:01 = 9:11 am.

Q. 17 If Priya is ready to board a train at 10:25 am from station T, then when is the earliest that she can reach station S?

Correct Answer

2

Explanation



There can be two routes that Priya can take.
Case 1: First travel by East-West line and then North-South line.
Trains leave after every 10 minutes on the East- West line.
The 10:20 am train from P reaches and then leaves T at = 10:20 + 00:11 + 00:02 = 10:33 am In the first case Priya will have to wait for 8 minutes at the station before boarding the train.
So let us see if the waiting time is reduced in case 2.
Case 2: First travel by North-South line and then East-West line.
Trains leave after every 15 minutes on the North- South line. The 10:15 am train from B will reach T at = 10:15 + 00:11 = 10:26 am and leave T at 10:28 am. In this case Priya’s train leaves within 3 minutes of her reaching the station. This train reaches R at = 10:28 + 00:15 = 10:43 am.
From R Priya has to catch the East-West train for station S.
The 10:30 am train from M reaches R at = 10:30 + 00:11 = 10:41 am and leaves at 10:43 am.
Priya can catch this train and reach station S at = 10:43 + 00:29 = 11:12 am.

Q. 18 Haripriya is expected to reach station S late. What is the latest time by which she must be ready to board at station S if she must reach station B before 1 am via station R?

Correct Answer

4

Explanation



The last (midnight) train from A reaches R at 12:11 am and leaves at 12:13 am. It will reach B at = 12:13 + 00:17 + 00:11 = 12:41 am.
From S to R the travel time is 29 minutes. To catch the 12:13 am train Haripriya will have to start from S at = 12:13 – 00:29 = 11:44 pm or before that.
Trains start from N after every 10 minutes and the time taken to reach S is 17 minutes.
There is a stoppage of 2 minutes at S.
The 11:30 pm train from N reaches S at 11:47 pm, which does not serve the purpose.
The 11:20 pm train from N reaches S at 11:37 pm and leaves at 11:39 pm.
This train will reach R by 11:39 + 00:29 = 12:08 am.
Then she can catch the last train from A going to B at 12:13 am.
Haripriya can catch the train at S if she reaches the station latest by 11:39 pm.

Q. 19 What is the minimum number of trains that are required to provide the service on the AB line (considering both north and south directions)?

Correct Answer

8

Explanation



Total time for a train to travel from A to B and to start back = 11 + 2 + 15 + 2 + 11 + 15 = 56 minutes.
Trains leave after every 15 minutes.
The minimum number of trains that are required to provide the service on the AB line (in the North-South direction) = [56/15] = [3.733] = 4 trains
Hence, for both directions = 4 + 4 = 8 trains.

Q. 20 What is the minimum number of trains that are required to provide the service in this city?

Correct Answer

48

Explanation



The minimum number of trains that are required to provide the service in this city
= Trains in AB and CD lines + Trains in MN and PQ lines.
Time taken for a train to travel from M to N and start back
= 11 + 2 + 29 + 2 + 17 + 15 = 76 minutes.
Trains leave after every 10 minutes on this line.
The minimum number of trains required on the MN line in the East-West direction
= [76/10] = [7.6] = 8 trains
Minimum number of trains required in both directions on the MN line = 16 trains Hence, total number of trains required
= (AB + CD) + (MN + PQ) = (8 + 8) + ( 16 + 16) = 48.
