Answer the questions on the basis of the information given below.
Coach John sat with the score cards of Indian players from the 3 games in a one-daycricket tournament where the same set of players played for India and all the majorbatsmen got out. John summarized the batting performance through three diagrams,one for each game. In each diagram, the three outer triangles communicate the numberof runs scored by the three top scores from India, where K, R, S, V, and Y representKaif, Rahul, Saurav, Virender, and Yuvraj respectively. The middle triangle in eachdiagram denotes the percentage of the total score that was scored by the top threeIndian scorers in that game. No two players score the same number of runs in the samegame. John also calculated two batting indices for each player based on his scores inthe tournaments; the R-index of a batsman is the difference between his highest andlowest scores in the 3 games while the M-index is the middle number, if his scores arearranged in a non-increasing order.
