C Correct answer
Explanation

Let third number = 100. First number = 65. Second number = 60. To make second equal to first, increase = 65 - 60 = 5. Percentage increase = (5 / 60) * 100 = 100 / 12 = 8.33%.

AI explanation

Let the third number be 100. The first number is then 65, and the second number is 60. To find the required percentage increase to make the second number equal the first, calculate the difference and divide by the original second number, which is (65 - 60) / 60. This equals 5 / 60, or 1/12, which is 8.33%.
