Ans1. No need to calculate simply looking at the graph gives us our ans. The lowest difference between white bar and grey bar is the ans. For understanding grey bar should be as close to white bar or more to get the lowest ratio of male(white bar) to female(grey bar). As we are dividing male by female. Only option D pediatrics come close.

Ans 2. Estimate the number of general surgery physicians by looking at the graph. Male = 35,000; female = 2000; total = 37000
calculate 3.5% * 37000 = 1295. This is the total number of females under 35 yrs category
Total number of general surgery physicians under 35 category = 30% * 37000 = 11100
If total number of females in the 35 under category = $$1295$$ than total males in this category is:
$$11100-1295 = 9805$$. Option B is the closest

Ans 3. From the graph white bar for general practice is approximately at 23000
Grey bar is approximately at 2000 so total would be 25000
male ratio to total would be $$\frac{23000}{25000}* 100 = 92%$$
approximately E is the closest

This seems like a ridiculously difficult question to be honest. Maybe not difficult but would be very time consuming for someone as slow as me.

Notoriously, MGRE has questions more difficult than real GRE.

For question 2, I found the reasoning in the answer above to be very hard to follow. So I am writing my explanation to help other people who may struggle such as me.

First, be very careful with the particular wording that they are using. They are saying "the number of female general surgery physicians in the under-35 category represented 3.5 percent of all the general surgery physician." The way that is represented is as follows:
x / 37000 = .035
x = 1295 women

Now, let's find the number of general surgery physicians under 35. The way we do that is we take a look at the bottom and second graph concurrently.
The total number of general surgery physicians from the top graph is 37,000. Now using the bottom graph, we have that 30% of them are under 35.
We use .3(37,000) = 11,000

Next, let's find the number of general surgery physicians under 35,
# of general surgery physicians under 35 = .3(37,000) = 11,000

Now, note that
# of general surgery physicians under 35 = # of general surgery physicians under 35 that are male + # of general surgery physicians under 35 that are female
11,000 = # males + 1295
So #male that are general surgery physicians under 35 = 9805
