$5$ people can do $5$ task in $5$ hours.

$1$ person can do $5$ task in $5*5$ hours. (Time taken would be more)

$1$ person can do $1$ task in $(5*5)/5 = 5$ hours. (Time taken would be less)

$3$ people can do $1$ task in $5/3$ hours. (Time taken would be less)

$3$ people can do $3$ task in $(5/3)*3 = 5$ hours.(Time taken would be more)
