Answer 1

Answer:

24 min

Step-by-step explanation:

capacity = LCM(30,45,36)

= 180 units

efficiency,

A => 180/30 = 6 units/min

B => 180/45 = 4 units/min

C can drain=>180/36 = 5 units/min

(A+B) fills together = 6+4 = 10 units/min

in 12 min = 12 × 10 = 120 units

remaining = 60 units

(A+B - C) together fills

= 6 +4-5 = 5 units/min

tank will be filled in

= 12 + (60/5) = 24 minutes
