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 / prakash
A takes 16 min for frist tank.. B and C circumfrence is 2:3... And A circum is one third of C so A is 1/3... Now
we have to fill twice the frist tank so A takes 32 min to fill.. B and C fills 5 time of A then ... So 32/5 is 6.4 min...
