Let capacity of pipe A = x m3 So, capacity of pipe B = x+ 24 m3 Required time to fill the swimming pool = 15120/x minutes Required time to empty the swimming pool = 15120/ (x + 24) minutes According to question – 15120/x – 15120 (x + 24) = 45/4 336/x – 336/ (x + 24) = 1/4 By solving, x = 168 m3 Capacity of second swimming pool = (168 + 24) × 100.5 = 19296m3
