Q2. Pipe A takes 16 min to fill a tank. Pipes B and C, whose
cross-sectional circumferences are in the ratio 2:3, fill
another tank twice as big as the first. If A has a
cross-sectional circumference that is one-third of C, how
long will it take for B and C to fill the second tank?
(Assume the rate at which water flows through a unit
cross-sectional area is same for all the three pipes.)

Answer Posted / manish thakur
Circumference units -> C = 1; B = 2/3; A = 1/3
Pipe cross sectional area units -> C = 1; B = 4/9; A = 1/9
Time = volume/ flow rate
Flow rate = constant x cross section area
Using the above, we can derive the time taken by B and C to
fill the tank, which twice the size of what A fills.
Solving, we get
Desired answer = 32/13
