Question
A certain number of men, represented as 'm', can finish
a task in 40 days. However, if there were 15 additional men, the same task would be completed in 25 days. find out the value of 'm'.Solution
According to the question, Total amount of work = 40 m units Therefore, 40 m = (m + 15) × 25 Or, 40 m – 25 m = 375 Or, m = 375/15 = 25Â
