Answer:
14/9 Days or 1+ 5/9 days
Step-by-step explanation:
In 4- days B and C complete =4/10+4/16
= 2/5 + 1/4
= (8+5)/20
= 13/20
The remaining (1–13/20) =7/20- part of the work is done by A and B.
The number of days in which the work will be done by A and Bus = 7/20/(1/8+1/10)
= 7/20/(18/80)
= 7/20 x 80/18
= 28/18
= 14/9 days.
