A Correct answer
Explanation

Given the ratio 8:9, we have 8/9 = 20/x. Solving for x, x = (20 * 9) / 8 = 180 / 8 = 22.50.

AI explanation

Let the two sums of money be 8x and 9x. Since the first sum is Rs. 20, we have 8x = 20, which gives x = 2.5. The second sum is 9x = 9 * 2.5 = Rs. 22.50. The other sum is Rs. 22.50.
