If the number of televisions which cleared the quality check (QC) on each of the given eight days is same, then at least how many refrigerators cleared the QC on day 3?
Explanation:
T-QC is same for all the days, then they should be in the form of 80k. LCM(4,8,2,5,10,16,5) T-total on day 3 = 90k T-total should be maximum to find the minimum value of refrigerators cleared QC. T-total maximum = 270 Number of refrigerators = 400 - 270 = 130 R-QC = R-total - R-defective = 130 - 100 = 30 Answer is option B.
