CAT4 - Number Analogies - Drill1

Choose the number that completes the third pair so that it demonstrates the same relationship as the first two pairs.

• 5

• 7

• 10

• 20

• 25

Answer explanation

正确答案是5。

观察第一对数字，尝试找出它们遵循的规则。

我们如何从40得到8？

我们发现，如果我们将第一个数字除以5，我们会得到第二个数字。40 ÷ 5 = 8。

这个规则对第二对数字也有效吗？

当我们将35除以5时，我们得到7。35 ÷ 5 = 7。

“将第一个数字除以5得到第二个数字”的规则在两对数字中都适用，所以下一对数字我们也应该除以5：

25 ÷ 5 = 5。

因此，5是正确答案。

Choose the number that completes the third pair so that it demonstrates the same relationship as the first two pairs.

• 24

• 30

• 32

• 36

• 40

Answer explanation

正确答案是36。

观察第一系列中的模式。10和30之间的差异是3的乘积。

10 x 3 = 30

第二系列也是如此，3和9之间的差异是3的乘积。

3 x 3 = 9

所以对于最后的系列，你也应该乘以3。

12 x 3 = 36。

?= 36。
