if 1,a=0,b=1,c=1,d=1,e=1,f=1 then it is 6 or if a=1,b=1,c=1,d=1,e=1,f=1 then sum if 7 or if a,b,c,d,e,f=0 then sum is 1

helo friends,
here the problem is not that you are thinking.you have to replace a,b,c,d,e &f with 0's and 1's and then you will find a set of 7 digit numbers. i think you have to use permutations & combinations here. At the end you will have to find the sum of all those 7 digit numbers.

Thank you
