A manufacturing plant produces 2 products (bolts and screws). 3% of all products are defective. If the ratio of products made is 3:2, respectively, and the percentage of bolts defective 5%, what percentage of screws are defective?  Choose the correct choice from the following answers:
A) 1/3%  B) 3%  C) 5%  D) 5/2%  E) 5/3%
Let B and S be number bolts and screws, respectively, and d represent defective.   B + S = total products.   B:S = 2:3   Bd/B = 5%   Sd/S = ?   [(2)(Bd/B) + (3)(Sd/S)]/(2 + 3) = 3%   [(2)(5%) + (3)(Sd/S)]/5 = 3%   Sd/S = 5/3%   Answer: 5/3%
