Answer the following 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 day cricket tournament where the same
set of players played for India and all the major batsman got out. John summarized the batting performance through
three diagrams, one for each gamE- In each diagram, the three outer triangles communicate the number of runs scored that
was scored by the three top scores from India, where K, R, S, V and Y represents Kaif, Rahul, Saurav, Virender and Yuvraj respectively. The middle triangle in each diagram denotes the percentage of the total score that was scored by the top three
Indian scorers in that gamE- No two players score the same number of runs in the same gamE- John also calculated two batting
indices for each player based on his scores in the tournaments; the R-index of a batsman is the difference between his highest and lowest scores in the 3 games while the M-index is the middle number, if his scores are arranged in a non-increasing order.
For how many Indian players is it possible to calculate the exact M-index?
