1.	5 skilled workers can build a wall in 20 days; 8 semi-skilled worker can build a wall in 25days; 10 unskilled workers can build a wall in 30 days, If a team has 2 killed, 6 semi-skilled and 5 unskilled workers, how long will it take to build the wall?
Answer» Given, 5 skilled workers can build a wall in 20 days i.e., 1 skilled worker can the wall build in 100 days ∴ The capacity of each skilled worker is 8 semi-skilled workers can build a wall in 25 days i.e., 1 semi-skilled worker can build a wall in 200 days ∴ The capacity of each semi-skilled worker is Similarly, The capacity of 1 unskilled worker is Now, The capacity of 2 skilled + 6 semi-skilled + 5 unskilled workers is ∴ The required numbers of days is 15.
