Answer:
2/3
Step-by-step explanation:
a can do 6 days
b can do 12 days
so A can do double work so work done by A is 2/3
Another method
A can do 6 days
ONE DAY WORK BY A =1/6
B can do 12 days
ONE DAY WORK BY A =1/12
One day work by A and B =1/6+1/12=2/12+1/12=3/12=1/4
TOGOTHER DO IN 4 DAYS
WORK DONE BY A IS 4x1/6=2/3
