Answer 1

Answer:

Hey mate here is your answer...

Step-by-step explanation:

Let the total capacity of the tank be 96 units (LCM of 24 & 32).

A fills =

24

96

= 4 units / minute.

B fills =

32

96

= 3 units / minute.

Let the time for which B is opened is x minutes.

According to the question, 4 × 18 + 3 × x = 96

3x = 96 - 72 = ⇒ 3x = 24

x = 8 minutes.

The pipe B should be closed after 8 minutes.
