Mujhe ppata hai ki yeh post karte hua teri dimagi halat kuch theek nahi thi as I can see the time of your post was 12.00 PM
is the answer six??(1,2,4,8,16,32)...
which book are u reading???
1st of all i re-read your entry and got the book's name...is it in French??...or is it just the title which is in French??
and about my answer..i just got it..you start with one..for two you need to have another weight..for three you could 2+1...for four you need another...each time you need another weight it is because the total of the other weight is less than the one you want to measure...
keep going and you'll get the others... it was actually the currency system that made me think this way...
