Answer:
% of women in the town= 100-(40+25)
= 100-65 = 35%
to find total number of people in town
17500 = x × 35/100
=(17500×100)/35
=50,000
(a)no of men = 50,000×40/100
= 20,000
(b) children = 50,000× 25/100
= 12500
Percentage of men = 40%
Percrntage of children = 25 %
Total percentage of men and children = 40% + 25% = 65%
therefore, Percentage of women = 100% - 65 % = 35 % ( let total population to be 100%)
It means 35% of the Total number of population were women.
35% of total population = 17500
35/100 of total popu. = 17500
Total population = 17500 × 100/ 35
= 50,000
Now the total population is 50,000
.
. . No. of men = 40/100 × 50000
= 20,000 Ans.
No.of children= 25 / 100 × 50000
= 12,500 Ans.
