Directions for questions (40 to 44): In the following, a year
corresponds to 1st of January of that year.
A study to determine the mortality rate for a disease
began in 1980. The study chose 1000 males and 1000
females and followed them for forty years or until they
died, whichever came first. The 1000 males chosen in
1980 consisted of 250 each of ages 10 to less than 20,
20 to less than 30, 30 to less than 40, and 40 to less
than 50. The 1000 females chosen in 1980 also
consisted of 250 each of ages 10 to less than 20, 20 to
less than 30, 30 to less than 40, and 40 to less than 50.
The four figures below depict the age profile of those
among the 2000 individuals who were still alive in 1990,
2000, 2010, and 2020. The blue bars in each figure
represent the number of males in each age group at
that point in time, while the pink bars represent the
number of females in each age group at that point in
time. The numbers next to the bars give the exact
numbers being represented by the bars. For example, we know that 230 males among those tracked and who were
alive in 1990 were aged between 20 and 30.

In 2000, what was the ratio of the number of dead
males to dead females among those being tracked?
