Question
A team of 12 men and 18 women can complete a
construction project in 24 days. If 6 women alone can do the same project in 144 days, how many days will 48 men take to complete the project alone?Solution
ATQ, Task done by 6 women in 1 day = 1/144 Task done by 18 women in 1 day = 3/144 = 1/48 Task done by 12 men = 1/24 – 1/48 = 1/48 Task done by 48 men = 4/48 = 1/12 Hence, required time = 12 days
