Question

In a city,40% are females,50%are males and the remaining are children.If total number of the children in the city is 200,find the population of city​

Answer 1

Step-by-step explanation:

Let the total no. of people in the city be 'x'

Percentage of females= 40%

Percentage of males= 50%

Total percentage=> (40+50)%=90%

Therefore, Remaining percentage of children will be=> (100-90)%=10%

Now, we know that the No. of children in the city is= 200

According to question,

10% of x = 200

=> 10/100 × x = 200

=> x= 200×100/10

=> x= 2000

Therefore, the total population of the city is 2000.

Answer 2

Percentage of males = 50%

Percentage of females = 40%

Total no. of people = 200

No. of men = 50/100 × 200 = 100

No. of women = 40/100 × 200 = 80

Total = 100+80 = 180

No. of children = 200 - 180 = 20

Hence, no. of children is 20.
