- The local office of the APP-CAB company evaluates the performance of five cab drivers, Arun, Barun, Chandan, Damodaran, and Eman for their monthly payment based on ratings in five different parameters (P1 to P5) as given below:
P1: timely arrival
P2: behaviour
P3: comfortable ride
P4: driver's familiarity with the route
P5: value for money
Based on feedback from the customers, the office assigns a rating from 1 to 5 in each of these parameters. Each rating is an integer from a low value of 1 to a high value of 5. The final rating of a driver is the average of his ratings in these five parameters. The monthly payment of the drivers has two parts – a fixed payment and final rating-based bonus. If a driver gets a rating of 1 in any of the parameters, he is not eligible to get bonus. To be eligible for bonus a driver also needs to get a rating of five in at least one of the parameters. The partial information related to the ratings of the drivers in different parameters and the monthly payment structure (in rupees) is given in the table below:The following additional facts are known.P1 P2 P3 P4 P5 Fixed Payment Bonus Arun 4 Rs. 1000 Rs. 250 × Final Rating Barun 3 Rs. 1200 Rs. 200 × Final Rating Chandan 2 Rs. 1400 Rs. 100 × Final Rating Damodaran 3 Rs. 1300 Rs. 150 × Final Rating Eman 2 Rs. 1100 Rs. 200 × Final Rating
Arun and Barun have got a rating of 5 in exactly one of the parameters. Chandan has got a rating of 5 in exactly two parameters.
None of drivers has got the same rating in three parameters. - Ten musicians (A, B, C, D, E, F, G, H, I and J) are experts in at least one of the following three percussion instruments: tabla, mridangam, and ghatam.

Due to a certain emergency situation, a few of the examinations could not be conducted for some students. Hence, some students missed one examination and some others missed two examinations. Nobody missed more than two examinations.
The board adopted the following policy for awarding marks to students. If a student appeared in all five examinations, then the marks awarded in each of the examinations were on the basis of the scores obtained by them in those examinations.
If a student missed only one examination, then the marks awarded in that examination was the average of the best three among the four scores in the examinations they appeared for.
If a student missed two examinations, then the marks awarded in each of these examinations was the average of the best two among the three scores in the examinations they appeared for.
The marks obtained by six students in the examination are given in the table below. Each of them missed either one or two examinations.English Hindi Mathematics Science Social Science Alva 80 75 70 75 60 Bithi 90 80 55 85 85 Carl 75 80 90 100 90 Deep 70 90 100 90 80 Esha 80 85 95 60 55 Foni 83 72 78 88 83
The following facts are also known.
I. Four of these students appeared in each of the English, Hindi, Science, and Social Science examinations. II. The student who missed the Mathematics examination did not miss any other examination.
III. One of the students who missed the Hindi examination did not miss any other examination. The other student who missed the Hindi examination also missed the Science examination. - 1000 patients currently suffering from a disease were selected to study the effectiveness of treatment of four types of medicines — A, B, C and D. These patients were first randomly assigned into two groups of equal size, called treatment group and control group.

A cricket tournament had three teams– India, Australia and Sri Lanka– taking part in it. The format of the tournament was such that in the preliminary stage each of these teams would play the other teams four times.
Four points are awarded for a win and in case a team beats another team by a huge margin, it is given a bonus point in addition to the four points.
At the end of the preliminary stage, the top two teams, in terms of the points scored, reach the finals.
No match in the tournament ends in a tie and if two teams end up with the same number of points at the end of the preliminary stage, the team with the better net run rate is placed higherTwo teams of five each must be selected from a group of ten persons — A through J — of which:
