Solution

The correct option is B $33000$
Population of Dodos in the year $1975 = 50000$
Population of Dodos in the year $1980 = 35000$
Population of Dodos in the year $1985 = 40000$
Population of Dodos in the year $1990 = 30000$
Population of Dodos in the year $1995 = 10000$

$M e a n = \frac{S u m o f t h e d a t a v a l u e s}{T o t a l n u m b e r o f v a l u e s}$

$M e a n = \frac{50000 + 35000 + 40000 + 30000 + 10000}{5}$

$M e a n = \frac{165000}{5} = 33000$ dodos
