Question

The mean proportion of two numbers is 24 and their third proportion is 72. Find the sum of the two numbers.

Answer 1

Given: The mean proportion of two numbers is 24 and their third proportion is 72.

To find: The sum of the two numbers

Step-by-step explanation:

Product of extremes = Product of means

72 × a = 24 × 24

a = 8

so, the sum of two numbers = 72 + 8

                                               = 80
