Solution

The correct option is C $6$
Given, the ratio of adults to girls to boys on a class field trip is $1 : 4 : 5$
Let $x$ be the common variable
Let number of adults be $x$ , number of girls be $4 x$ and number of boys be $5 x$ .
Since the trip included $6$ more boys than girls,
$5 x - 4 x = 6$
$x = 6$
Therefore $6$ adults were with the group.
