Percentage of male in the town =40%
Percentage of female in the town =30%

Percentage of children in the town =(100−(40+30))%=30%
Total population of the town =200000
Therefore,
Total no. of children in the town =
100
30
​
×200000=60000
Hence the number of children in the town is 60000.

Answer 2

Given:-

Total population=200000

Percentage of male=40%

Percentage of female=30%

To find:-

Number of children

Solution:-

Percentage of male+Percentage of female+Percentage of children=100%

40%+30%+Percentage of children=100%

Percentage of children=(100-40+30)%

=30%

Thus,number of children=30% of 200000

30/100×200000

=6000000/100

=60000

Hence,the number of children is 60000
