Question has asked to mark yes if the ans to the part is between 40 to 60% else mark no

So 1st part says
B comprises what % of total dose in patient of Median age
Here sorting age column, we get Median age as 35 and that patient has 4.1 as dose of B out of 8.7 in total. So it's 47%. 47% is in between 40 and 60% so we will mark yes

Next says Median age of female to Median age of male.

Sorting again and noting age of female only, we get Median as 41 for female
For male it was 35. So it's 6 more than male and that is nearly 17% (6/35) which do not lie between 40 to 60% and hence we will mark it as No

Hope this clarifies!
