Consider two tanks - T1 & T2 such that the volume of T2 is twice that of T1. T1 is fitted with 1 pipe A of circular cross-section, whereas T2 has 3 pipes – P, Q & R of circular cross-sections. The ratio of diameters of P, Q & R is 1 : 2 : 3. P’s cross-sectional area is 7 times A’s cross-sectional area. A takes 10 min to fill T1. Find the time taken to fill T2, if all the 3 pipes are opened.
