Answer» (A+B)'s 1-day work, when working TOGETHER= 1/30 (A+B)'s 20 days' work= 20/30==> 2/3 REMAINING work = (1-2/3) ===> 1/3 Remaining work was done by A in 20 more days = 1/3 So A can COMPLETE the whole work alone in = 20* 3 ===>60 days Hence A's 1-day work, working alone = 1/60 B?s 1 day work, working alone = 1/30-1/60======1/60 So B will take 60 days to for completing the entire word. (A+B)'s 1-day work, when working together= 1/30 (A+B)'s 20 days' work= 20/30==> 2/3 Remaining work = (1-2/3) ===> 1/3 Remaining work was done by A in 20 more days = 1/3 So A can complete the whole work alone in = 20* 3 ===>60 days Hence A's 1-day work, working alone = 1/60 B?s 1 day work, working alone = 1/30-1/60======1/60 So B will take 60 days to for completing the entire word. |
