A disease has infected an ant colony that consists ofworkersandsoldiers: 30% of the soldiers and 14% of theworkerswere infected. If that colony is inhabited by 7000 ants, out of which 1580 are infected, how manyworkersinhabit the colony?  Choose the correct choice from the following
A) 1500  B) 2500  C) 2750  D) 3000  E) 3250
From two question we get wo equations:   (1) 0,3s + 0,14w = 1580   (2) s + w = 7000   From (2) we get w=7000-s   In (1) 0,3s + 980-0,14s= 1580   0,16s=600   60000:16= 3750 =s   In (2) 3750 + w = 7000   w= 3250 3250
