16 workers working 8 hours per day can demolish building in days = 32 (MDH)/W = CONSTANT where, M = Number of people, D = Number of days, H = Number of hours, W = Work done |

Let 24 workers working 12 hours a day can demolish building in x days. ATQ - (16 × 8 × 32)/1 = (24 × 12 × x)/1 9x = 128 x = 128/9 days |
