Six girls can complete a piece of work in 5 days, whereas 10 boys take 4 days to complete the same work. In how many days can 3 girls and 6 boys together complete the work?

Problem Statement

1 girl efficiency = 1/(6×5). 1 boy efficiency = 1/(10×4). Total efficiency = 3/(30) + 6/(40) = 0.1 + 0.15 = 0.25 → Work in 1/0.25 = 4 days.
