If you divide the ball in 3 groups , how are you going to weigh 3 groups against each other ?
Lets say you get lucky and get it in first group then how are you going to compare the weight of other two ?
I guess you would need minimum 3 times to measure it , right ?
Let me know as I am just a high schooler and would like to know know more about this topic .
Thanking you,
