Question

there are total number of people in party is 94 consisting of male and female.fifth part of male and eight part of female are in the ratio 3:4.if out of all the males 50%are married while out of total female 25% females are married,then find the % of unmarried people

Answer 1

Let the number of males be x and females be y.

Given that fifth part of male and eighth part of female are in ratio 3:4,

 x/5: y/8 = 3/4

x/y = 15/32.

Then total males = 15/15+32 * 94

                             = 15/47 * 94

                            = 30.


Then total females = 32/32 + 15 * 94
 
                                = 64.

Given that 50% male are married and 25% females are married = (100-25) = 75


Then the % of unmarried people = 50/100 * 30 + 75/100 * 64/94

                                                        = 67%.


Hope this helps!
