A alone can make a table in 30 days while B alone can make it in 15 days. B started the work alone and worked for 8 days. In how many days A alone can finish the remaining work ?

14 days

A = 30 days,

B = 15 days,

⇒ B worked for 8 days alone = 2 x 8 = 16 units ..(Efficiency × Days = Work)

⇒ Remaining work = 30 - 16 = 14 units.

⇒ Time required for A to complete 14 units = \(\frac{14}{1}\) = 14 days. ..(\(\frac{Work}{Efficiency}\) = Time)
