from ARUN SHARMA number system lod 3

in a 11 player cricket team (having 1 to 7 bowlers) by using the no of wickets taken by each bowler and attachingg coefficients of +1,0 or -1 to each value available and adding the resultant values any number from 1 to 1093 can be formed
. if we denote w1,w2,w3,w4,w5,w6,w7 as the values in the ascending order.ansr the follwoing questions
;
1.) w1+2 (w2) + 3(w3) +4 (w4) +5 (w5) +6 (w6)=?
2.) find the index of 3 in w1*w2*w3*w4*w5*w6*w7
3.) if the sum of seven coefficients is 0, find the smallest number that can be obtained.
