17
Solution :
The correct answer is 17.
Step 1: Calculate the mean proportional of 75 and 12.
The mean proportional between two numbers a and b is given by the formula:
Substitute a = 75 and b = 12 into the formula:
Step 2: Subtract 13 from the mean proportional.
According to the question, subtract 13 from the mean proportional obtained above:
