An assembly line produces 500 vehicle parts daily. The line produces only car parts and truck parts in a ratio of 2 : 3 and the ratio of defective car parts to defective truck parts is 1 : 2. If 6 parts on a certain day are defective, how many non-defective car parts are produced on that day?
A. 2
B. 4
C. 6
D. 20
E. 198
Number of vehicle parts produced per day = 500
Number of car parts = 2/5 * 500 = 200
Number of truck parts = 300
Ratio of defective car parts to defective truck parts is 1 : 2
Number of defective parts produced on a day = 6
number of defective car parts = 1/3*6 = 2
Number of non-defective car parts = 200 - 2 = 198
Answer E
