Question

Q.35. One effective way of ascertaining population size of an animal species in wild is
to capture a certain number, mark them and release in the habitat. After a duration,
catch another batch of animals and find out how many among them are marked. From
the ratio of marked to unmarked individuals, total number of animals can be
computed. In a workout, 10 marked individuals were released in wild and after a
week, a batch of 12 was captured among which 2 were found to be marked. The size
of the population would be:
a) 40
b) 60
c) 80
d) 100​
