Ops: A. 36 minutes
B. 30 minutes
C. 32 minutes
38 minutes

Answer 1

Answer:

A : 36minutes

Step-by-step explanation:

Pipe C fills the tank in 24 minutes

Let pipe Y fills the tank in x minutes

now,

water filled by pipe c in 1 minute =1/24

water filled by pipe Y in 1 minute=1/x

and water filled by pipe c along with pipe y=1/14.4 =10/144=5/72

Now, according to question

1/24+1/x=5/72

1/x=5/72-1/24

1/x=5-3/72

1/x=2/72

1/x=1/36

x=36
