Answer:
Step-by-step explanation:
Given : 3/5 as men as women means-
Men = 3/5 Women
2/3 of the men wear = 2/3 x 3/5women
= 2/5 w
1/5 of wmen wear, = 1/5w
No. of men who do not wear = 3/5w - 2/5w
= 1/5w
No. of women who do not wear = w-1/5w
= 4/5w or 4w/5
No of ppl who do not wear F.D =
1/5w + 4/5w = 5/5 w
= w
total no. of ppl in the hall = men + women
= 3/5w + w
=8/5w
Ratio = No of ppl wear : Total ppl
= w: 8/5w
= w x 5/8w
= 5/8
= 5:8 Ans. (c)
