​

Answer 1

Answer:

6 days

Step-by-step explanation:

As they have given, Pipe b works for 1/4 times of total  work and same for pipe A

pipe a worked for 20 hours, so 4 times 20 = 80 hours

pipe b worked for 16 hours, so 4 times it will be 16*4 = 64

total time = 80+64 = 144 hours

days = 144/ 24 hours = 6 days
