  w' n9 G8 K6 Otvb now,tvbnow,bttvb第一种:1.放完第一同第二粒时,天平已经倾斜咗,即係其中一粒係异常,2.攞起任意一粒,将剩低果粒同第三粒比' R: U  l( y& g8 d' t( N' j
第二种:1.第一同第二粒重量一样,继续加,加到个天平倾斜为止(前提係两边波既数量要一样),最后放落去果粒或倒数第二粒就係异常2.重复第一种情况第2步公仔箱論壇' \5 D- M" A& z5 z& k' d% m

抽其中两个称,如果重量相等,则没有被选中嘅球系最重/輕的。如果重量不等,则重/輕的那一边就是那个ball了

FIRST PLACE 6 BALLS ON EACH SIDE OF THE LIBRA. ONE SIDE MUST BE HEAVIER THAN THE OTHER IF ONE OF THE BALL WEIGHT MORE. NOW WITH 6 BALLS LEFT, PLACE 3 BALLS ON EACH SIDE OF THE LIBRA. THE WEIGHT DIFFERENCE WILL ELIMINATE 3 MORE BALLS. WITH 3 BALLS LEFT, JUST PICK 2 BALLS AND PLACE THEM ON THE LIBRA. IF THE WEIGHT ARE THE SMAE. THEN THE BALL NOT ON LIBRA WILL BE THE HEAVIER BALL.

先把12 分为 4組每組3个, 先把1組同2組称, 3组同4组称.最后,把差别最大的再称抽其中两个称,如果重量相等,则没有被选中嘅球系重量異常的。
