Incorrect AnswerExplanation:
Given monday population = 3000
Per day 20% increase in population.
Tuesday population = 3000 + 3000x20/100
= 3000 + 600 = 3600
Wednesday population =3600 + 3600x20/100
= 3600 + 720 = 4320
Thursday population = 4320 + 4320x20/100
= 4320 + 864 = 5184
So that day is Thursday.
Hence, option 3 is the correct answer.
