Finding the Fourth Proportional

Understanding the concept: Four numbers a, b, c, and d are said to be in proportion if a:b = c:d. Here, d is called the fourth proportional to a, b, and c.

Solution: Let the fourth proportional be x.

So, we have:

60 : 48 = 30 : x

Cross-multiplying, we get:

60 * x = 48 * 30

Solving for x:

x = (48 * 30) / 60
x = 24

Therefore, the fourth proportional to 60, 48, and 30 is 24.

So, the correct answer is (C) 24.
