In a country , 60% of the male citizen and 70% of the female citizen are eligible to vote. 70% of male citizens eligible to vote voted and 60% of female citizens eligible to vote voted. What fraction of the citizens voted during the election ? Correct Answer 21/50

Let, male citizen = x, female = y Male voted = x × 60/100 × 70/100 Female voted = y × 70/100 × 60/100 So, fraction of citizen voted = {(4200/10000)x + (4200/10000)y}/(x + y) = 21/50
