Question

there are total 94 people in a party consisting of male and female fifth part of the male and eight part of the female are in the ratio 3 : 4 if out of all the males 50% are married while out of the total female 25% females are married then find the percent of unmarried people(approx)

Answer 1

m÷5:f÷8=3:4
m plus f=94
on solving both equations
m=30,f=64
50%of m=15
75% of f=48
no. of unmarried people =63
in percentage =63÷94*l00=67.7
