Sample Questions

1multiple correct

Which of the following are properties that can be applied to proportions? (Select all correct)

Show answer

Invertendo, Alternendo, Componendo, Dividendo

The four main properties of proportions are: Invertendo (a:b = c:d → b:a = d:c), Alternendo (a:b = c:d → a:c = b:d), Componendo (a:b = c:d → (a+b):b = (c+d):d), and Dividendo (a:b = c:d → (a-b):b = (c-d):d).

2multiple choice

Find the mean proportional between 9 and 16.

Show answer

12

If x is the mean proportional between 9 and 16, then 9:x = x:16. Cross multiply: x² = 9 × 16 = 144. Therefore x = √144 = 12.

3multiple choice

What is the sub-duplicate ratio of 25:36?

Show answer

5:6

Sub-duplicate ratio of a:b is √a:√b. So sub-duplicate ratio of 25:36 is √25:√36 = 5:6.

4multiple choice

If x/3 = y/5 = z/7, and x + y + z = 45, find the value of z.

Show answer

21

Let x/3 = y/5 = z/7 = k. Then x = 3k, y = 5k, z = 7k. Given x + y + z = 45, so 3k + 5k + 7k = 15k = 45. Therefore k = 3, and z = 7k = 7(3) = 21.
