Question 103

A can do a piece of work in 12 days and B in 24 days. If they work together, in how many days will they finish the work ?

Solution

Work done by working together = $$\frac{1}{12}+\frac{1}{24}$$

= $$\frac{2+1}{24}=\frac{3}{24}=\frac{1}{8}$$

$$\therefore$$ Time taken = $$\frac{1}{\frac{1}{8}}=8$$ days

=> Ans - (D)
