Question

Answer 1

1980

Explanation:

Answer 2

462

Explanation:

Total number of people on the cruise ship was 1320.

`(1)/(4)^(th)` of the people were child passengers. Number of child passengers =
`(1)/(4)* (\text{Total number of people})=(1)/(4)* 1320=330`

`(2)/(5)^(th)` of the people were crew. Number of people that were crew =
`(2)/(5)* (\text{Total number of people})=(2)/(5)* 1320=528`

Remaining people in the ship constitute the adult passengers.

Number of adult passengers =
`(\textbf{Total number of people})-(\textbf{Total number of children})-(\textbf{Total number of crew})=1320-330-528=\textbf{462}`

∴ Number of adult passengers = 462
