Alright agyenim — let's do this. The problem asks us to find the values of P and K from a frequency distribution table, given that the mean mark is 24.75. First, we need to determine the midpoint (x) for each class interval. There appears to be a typo in the table for the third class, "21-20". Given the pattern of the other class intervals (e.g., 11-15, 16-20, 26-30), it is highly probable that "21-20" should be "21-25" to maintain a consistent class width and logical progression. We will proceed with this assumption. Step 1: Calculate the mid
