13. The population of two villages is 1525
and 2600 respectively. If the ratio of
male to female population in the first
village is 27: 34 and the ratio of male
to female population in the second
village is 6:7, then what is the ratio
of male to female population of these
two villages taken together ?​

Answer 1

village 1

let population of  male & female be "x"

so 27x+34x=1525

       61x+1525

        x= 1525/61

          x=25

male in village1= 25*27=675

females in village1=25*34=850

village 2

let population of males and females be y

so 6y+7y=2600

    13y=2600

    y=2600/13

   y=200

number of male=200*6=1200

number of females=200*7=1400

Answer 2

Answer:

5 : 6

Step-by-step explanation:

Village A=1525   Ratio male to female= 27 : 34

Village A - 27x+34x=1525           Male = 27x             Female = 34x

                          61x=1525                    = 27(25)                      = 34(25)

                              x=25                       = 675                          = 850

Village B=2600  Ratio male to female= 6 : 7

Village B - 6y+7y=2600              Male = 6y              Female = 7y

                      13y=2600                       =6(200)                      =7(200)

                          y=200                         =1200                         =1400

Ratio of Male to Female together

Village A+B=4125

Male in village A+B=1875

Female in village A+B=2250

Ratio of Male : Female

             1875 : 2250

     1875÷375 : 2250÷375

                   5 : 6
