Answer:

Given:

Monday population $= 3000$

Per day 20% increase in population.

Tuesday population

$= 3000 + \frac{3000 \times 20}{100}$

$= 3000 + 600$

$= 3600$

Wednesday population

$= 3600 + \frac{3600 \times 20}{100}$

$= 3600 + 720$

$= 4320$

Thursday population

$= 4320 + \frac{4320 \times 20}{100}$

$= 4320 + 864$

$= 5184$

So,

That day is Thursday.

Therefore,

Correct option A) Thursday.

Q:

Population of a colony of mosquitoes is increasing by 20% per day. If the population on Monday was 3000, on which day of that week the population would be 5184 ?

A) Thursday
B) Friday
C) Tuesday
D) Monday

Answer:   A) Thursday 

Explanation:

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.
