The captain must have been "not out" and scored 21. Thus:--

2 men (each lbw) 19

4 men (each caught) 17

1 man (run out) 0

3 men (each bowled) 9

1 man (captain--not out) 21

-- --

11 66

The captain thus scored exactly 15 more than the average of the team.

The "others" who were bowled could only refer to three men, as the

eleventh man would be "not out." The reader can discover for himself why

the captain must have been that eleventh man. It would not necessarily

follow with any figures.
