Respuesta :
462
Step-by-step explanation:
Total number of people on the cruise ship was 1320.
[tex]\frac{1}{4}^{th}[/tex] of the people were child passengers. Number of child passengers = [tex]\dfrac{1}{4}\times (\text{Total number of people})=\dfrac{1}{4}\times 1320=330[/tex]
[tex]\frac{2}{5}^{th}[/tex] of the people were crew. Number of people that were crew = [tex]\dfrac{2}{5}\times (\text{Total number of people})=\dfrac{2}{5}\times 1320=528[/tex]
Remaining people in the ship constitute the adult passengers.
Number of adult passengers = [tex](\textbf{Total number of people})-(\textbf{Total number of children})-(\textbf{Total number of crew})=1320-330-528=\textbf{462}[/tex]
∴ Number of adult passengers = 462
