At a particular time in the 21st cebtury there were seven bowlers in the indian cricket team's list of 16 players shortlisted to play the next wc . Statisticians discovered that if u looked at the no of wickets taken by any of the 7 bowlers in the current indian cricket team , the number of wickets taken by them had a strange property . The numbers were such that for any team selection of 11 players (having 1 to 7 bowlers) by using the number of wickets taken by each bowler and attaching coefficients 0f +1 , 0 , -1 to eachvalue available and adding the resultant values , any number from 1 to 1093 both included could be formed . If we denote W1,W2,W3,W4,W5,W6,W7 as the 7 values in the ascending order what would be the answer to the following questions :47) Find the value of W1+2W2+3W3+4W4+5W5+6W6a) 2005 b) 1995c)1985 d)NOT4 Find the index of the largest power of 3 contained in the product W1 W2 W3 W4 W5 W6 W7a) 15 b) 10c) 21 d) 649) If the sum of the seven coefficients is 0 , find the smallest number that can be obtained a) -1067 b)-729c) -1040 d) -1053
