Ratio and Proportion: Sub-Duplicate Ratio

Explanation:
Sub-Duplicate Ratio: If the ratio of two numbers is a:b, then their sub-duplicate ratio is √a : √b.

Given, the sub-duplicate ratio of 25:36.

Let the numbers be x and y.

√x/√y = 25/36

Squaring both sides, we get

x/y = (25/36)^2

x/y = 625/1296

x:y = 625:1296

Therefore, the required ratio is 5:6

Hence, option D (5:6) is the correct answer.
