Answer:
Let assume the work is = 1 unit
two mens are there , man A and man B.
Man A does this work in = 10 day
so 1 day work of A = 1/10 unit
similarly 1 day work of B = 1/15 unit
if both works together than
1 day work of both (A+B) = [ 1/10 + 1/15 ] = 1/6 unit
total days to complete the work = Total Work ÷ one day work of (A+B)
⇒ = 1/(1/6)
⇒ = 6 days
