Best ResponseYou've already chosen the best response.1Thinking it backwards, you have six weights, and you can choose them to form different weights. i.e., choose one and two, and you get three. choose 32 and 1 and you get 33. You can choose or don't choose the weights to form the weights. So, with six weights, ways to choose is (choose) or (not choose)for each weight thus, is 2*2*2*2*2*2=64 with 4 gone, we are left with 5 weights. thus, similarly, 2*2*2*2*2=32 ANS is 6432=32
