उत्तर
Given that
Volume of cinema hall = `100xx50xx18m^3`
Volume air required by each person = `150m^3`
Number of person who can sit in the hall
`= "volume of cinema hall"/"volume of air req each person"`
`=(100xx50xx18m^2)/(150m^3)=600 [∴v=lxxbxxh]`
∴number of person who can sit in the hall
`= 600 members `
