用线索推第三组 = cari kumpulan ketiga 先用“一样多”的线索写出 B 组的人数，再用总数减去 A、B 两组。 例子：总数 30，A 8，B 和 A 一样：30 − 8 − 8 = 14。 注意：最后把三组加起来检查一次，一定要等于总数。

using clues for the third group = cari kumpulan ketiga Use the 'same as' clue to write down group B, then subtract groups A and B from the total. Example: total 30, A has 8 and B equals A: 30 − 8 − 8 = 14. Watch out: add all three groups at the end; they must equal the total.

相差的推理 = beza dua balang 先拿掉多出的 6 粒，剩下的平分，就是比较少的那一瓶。 例子：两瓶共 20，一瓶多 4：(20 − 4) ÷ 2 = 8。 注意：P 比较多，Q 比较少；算完把两瓶加起来，看看是不是等于总数。

two jars that differ = beza dua balang Remove the extra 6 first, then share the rest equally; that is the smaller jar. Example: two jars total 20 and one has 4 more: (20 − 4) ÷ 2 = 8. Watch out: P has more and Q has fewer; afterwards add the two jars to check they make the total.

检查推出的数据 = semak data 推出每一项以后，最有用的检查是把全部数字加起来，看是不是等于题目给的总数。 例子：推出 5、7、8，总数应该是 20。 注意：颜色和字体不会影响数据对不对，只有加起来等于总数，才能确定推出的数据没有错。

checking the data you found = semak data After finding each item, the most useful check is to add all the numbers and see if they equal the total given in the question. Example: if you found 5, 7 and 8, the total should be 20. Watch out: colours and lettering do not affect whether the data are correct; only adding up to the total confirms the numbers.
