The question, as most of the other table questions, can be answered straight forward from the table without much of calculations.
Having said that, accuracy and speed becomes utmost important.
1. Median Age: Since we are looking for median age of ranch and foyers, sort table by the year of construction.
Look at the column of type of style. There are six of each type, so the median year of construction would be the average of 3rd and 4th house in respective styles.
We don't require to check anything. All six of the Split Foyer have been constructed prior to four of the ranch, so surely the median year of construction is larger for Ranch, thereby indicating that median age of split foyer is more....Split Foyer
2. Price Range: Sort table by price or type of style.
One can find ranch cost somewhere > $100k to >$300k , so range is at least 150k or so. However, all the split foyer are within 100k and 200k, so range is surely more for Ranch...Ranch
3. Ratio of mode number of bathrooms to mode number of bedrooms: Sort the table by style and check modes for each category.
Mode number of bathrooms: Ranch - 3, and Split Foyer - 1 and 1.5
Mode number of bedrooms: Ranch - 4, and Slit Foyer - 4
Thus, mode number of bathrooms to mode number of bedrooms = > Ranch - 3/4 and Split Foyer - 1/4 or 1.5/4
3/4 is greater than both 1/4 and 1.5/4....Ranch

Mode number of bathrooms: Ranch - 3, and Split Foyer - 1 and 1.5
Mode number of bedrooms: Ranch - 4, and Slit Foyer - 4
Thus, mode number of bathrooms to mode number of bedrooms = > Ranch - 3/4 and Split Foyer - 1/4 or 1.5/4
3/4 is greater than both 1/4 and 1.5/4....Ranch

Answer for Ratio of mode number of bathrooms to mode number of bedrooms
They are asking for mode (the number in a data set that appears the most number of times).
Mode of Ranch (Bathrooms) = 3
Mode of Ranch (Bedrooms) = 4
Ratio of mode number of bathrooms to mode number of bedrooms = 3:4 = 0.75
Mode of Split Foyer (Bathrooms) = Since 1 and 1.5 both appear 2 times, this set has 2 modes (Bimodal distribution- I just googled it). Im stuck here as well.
Although I did find out the ratio of both the possibilities (using 1 and 1.5 in the Ratio of mode number of bathrooms to mode number of bedrooms)
Case 1 - Mode of Split Foyer (Bathrooms) = 1
Case 2 - Mode of Split Foyer (Bathrooms) = 1.5
Mode of Split Foyer (Bedrooms) = 3
Case 1 - Ratio of mode number of bathrooms to mode number of bedrooms [where Mode of Split Foyer (Bathrooms) = 1] = 1:3 = 0.33
Case 2 - Ratio of mode number of bathrooms to mode number of bedrooms [where Mode of Split Foyer (Bedrooms) = 1.5] = 1.5:3 = 1:2 = 0.50
0.75 (Ranch) > 0.33 (Split Foyer: Case 1)
0.75 (Ranch) > 0.50 (Split Foyer: Case 2)
So Ratio of modes under Ranch > Ratio of modes under Split Foyer in all cases.
I couldn't get this right in the first go. I think this is the logic. Please correct me if I am wrong.
