Discuss
Answer & Solution
Percentage of people below 36 years
= (20 + 18.25 + 16.75)%
= 55%
55% = 22 millions
$$\eqalign{ & 1\% = \frac{22}{55} \cr & 12.5\% = \frac{22}{55} \times 12.5 \cr & \,\,\,\,\,\,\,\,\,\,\,\,\, = 5 \text{ millions} \cr}$$

If the different between the number of people in the age groups (46 - 55) and (16 - 25) is 0.975 million, then the total population (in millions) of the city is:
Discuss
Answer & Solution
Difference = 0.975 millions
(18.25 - 15)% = 0.975 millions
3.25% = 0.975
$$\eqalign{ & 1\% = \frac{0.975}{3.25} \cr & 100\% = \frac{0.975}{3.25} \times 100 \cr & \,\,\,\,\,\,\,\,\,\,\,\, = 30 \text{ millions} \cr} $$
