For question 44, the answer explanation was that first we find the proportion of men and women who can hear using the ratio in the table:
i.e.
for men = 100000 x 21/139 = ~15108
for women = 100000 x 30/102 = ~29412
and then calculate the percentages of these hearing adults who are under 25
for men = 15108 x 0.991 = 14972
for women = 29412 x 0.986 = 29000
and sum to get answer around 43870 answer D
but isn't the question asking for adults under 25 (i.e. 18<x<25) in total? not those who can hear?
methinks the answer is wrong - anyway please send me some harder QR questions you have found because i am struggling more for this section that I thought i would
thanks!
