If 2/3 of the number of women attending a certain art competition is equal to ½ the number of men attending, what fraction of those attending are women?
Solution
Correct Answer: Option B
মনেকরি,
প্রতিযোগীতায় উপস্থিত মহিলা= w
প্রতিযোগীতায় উপস্থিত পুরুষ= m
প্রশ্নানুসারে,
2/3 w = 1/2 m
⇒ w = (1/2)*(3/2)m
⇒ w = 3/4 m
সুতরাং, মহিলা রয়েছে = w/(w+m)অংশ
= (3/4m)/(3/4m + m)
= 3/7 অংশ
