B joined him. If they complete the work in 3 more days, in how many days can B alone finish the work ? After 3 days A finishes 3 units. work left =12−3=9 units

Answer 2

Answer:

64 days

Step-by-step explanation:

3 days -->$\frac{3}{12}$

1-$\frac{3}{12}$=$\frac{9}{12}$

$\frac{9}{12}$=$\frac{3}{4}$

48÷$\frac{3}{4}$= 48×$\frac{4}{3}$=64 days
