A can finish a work in 24 days, B in 9 days and C in 12 days. B and C start the work but are forced to leave after 3 days. The remaining work was done by A in:

Answer»

10 DAYS



No. of days TAKEN by B and C together to finish the work = 9 × 12/21 = 36/7 days 

Their 1 DAY work = 7/36 

So, their 3 day’s work = 7/36 × 3 = 7/12 

The remaining work = 5/12 

A’s 1 day’s work = 1/24 

To finish the remaining 5/12 of the work, the No. of days taken by A = 5/12/1/24 

= 5/12 ×24= 10 days.
