Answer» Answer: A takes 8 DAYS to FINISH x amount of WORK. B takes 10 days to finish x amount of work. Work completed in 1 day by A= 8 x
Work completed in 1 day by B= 4 x
Work completed in 1 day by A and B = 8 x
+ 4 x
= 8 3x
Days TAKEN to complete x amount of work by A and B = work completed x
= 8 3x
x
= 3 8
