Question
A2 type ‘P’ pipes can fill
a tank in 450 hours, while B2 type ‘Q’ pipes can fill the same tank in 648 hours. (10A × 6B) type ‘P’ pipes can fill the same tank in how many hours? (Efficiency of a type P and a type Q pipe is same)Solution
A2 × 450 = B2 × 648
A2/B2 = 648/450
A2/B2 = 36/25
A/B = 6/5
A = 6B/5
(10A × 6B) type 'P' pipes = 10 × 6B/5 × 6B = 72 B2
Required time = (B2 × 648)/(72 × B2) = 9 hrs
