Question

in a theatre for a show 1/2 the audience were women and 1/3 of these women were school girls if total audience were 600 in number how many were school girls

Answer 1

As per question,
total audience = 600
number of women in theatre =600/2
= 300
again 1/3 of women's population in theatre is school girls,
so no of school girls in theatre = 1/3 × number of women audience
= 1/3 × 300
= 300/3
=100
Hence, the number of school girls in the theatre is 100.//

Answer 2

according to the question, total audience are 600
so,women's are-1/2 of the audience
therefore,women's are 600/2=300.
1/3 of the women's are school girls
so,school girls are 600/3=100

Hence,the no. of school girls are 100
