Answer 1

Answer:

C can do a piece of work in 24 days.

$\pink{Explanation}$

Since we have given that

Number of days in which A and B can do a piece of work = 3 days

Number of days in which B and C can do a piece of work = 4 days

Number of days in which C and A can do a piece of work = 6 days

So, total number of units = L.C.M. of 3, 4, 6 = 12

So, the number of days in which C can alone do the work is given by

$\frac{12 \times 2}{3 + 2 - 4} = \frac{24}{1} = 24 \: days$

Hence , C can do the work in 24 days
