Question

The total population of a village is 5000. The number of males and females increases by 10% and 15% respectively and consequently the population of the village becomes 5600. What was the number of males in the village ? Select one:

a. 4000

b. 2500

c. 2000

d. 3000

Answer 1

Step-by-step explanation:

ans is (c)

because

suppose number of males =m

and number of females =f

so m+f=5000

after increase males by 10% m1=110m/100

and female by 15% f1=115f/100

and m1+f1=5600

so putting values of m1 and f1

equation become 110m+115f=560000

after solving both equations we get f=2000 and m=3000

so no of males =3000 answer is (c)

Answer 2

3000
Because the number of men and women before increased is 2500 and 2500 each and then men became 15%more then it becomes 3000
