Q: In his company, Kenzo has 80 office chairs with five legs each and 20 round tables with three legs each. If after a month 40% of the chairs are damaged and have to be disposed of, calculate the total number of legs of furniture Kenzo has remaining in his company.
A: The number of chairs that are disposed of after they're found to be damaged is 40 / 100 * 80 = 32. The number of chairs in good condition in Kenzo's company is 80 - 32 = 48. The 48 chairs have 48 * 5 = 240 legs. The round tables also have 20 * 3 = 60 legs. In total, the furniture in Kenzo's company has 60 + 240 = 300 legs. The answer is 300.
