Answer: in order to maximize efficiency of this balancer you put four of the coins on the balancer and then you do it again and record both of how much each set of four coins weigh and you see that eg B's set of coins weighs more so then you divide As weigh by 4 and then you see that (whatever number it is) should be what the answer is then you divide Bs by four (with the odd one out) depending on how much heavier it is you would just take away from the weigh until it Raquel's what A equals then you would add that then whatever B divide by four equals you would add however many of the remainder of B and ad dit to the answer of B divided by four... done that's how you do it
