After a one week interval the students went back into the field and caught a total of 250 lizards out of which 150 bore the indelible ink mark.

According to pg 99 of mordern biology, to calculate this problem you:
1) MULTIPLY the no of animals caught and counted, marked with ink and released on the first day...(360) by the no of animals recorded...(250)
2) DIVIDE YOUR VALUE BY THE no of animals marked from the previous day that were also marked(150)
THEREFORE TO SOLVE THIS PROBLEM... YOU DO...
A1*A2/A3
[360*250]=90000
90000/150=600
THEREFORE CORRECT ANS IS (E)
