A cylinder P of radius 14 m and height 44 m pierces through another cylinder Q whose radius is thrice the radius of cylinder P and height is ;i. times of the cylinder P as shown in the figure below. Two different liquids are poured simultaneously in both the cylinders at the rate of 44 m3/minute in cylinder P and at the rate of 64 m3/ minute in cylinder Q, till the cylinders are filled up to the brim. The time taken to completely fill the two cylinders is
  • a)
    8 hours and 48 minutes
  • b)
    4 hours
  • c)
    20 hours and 32 minutes
  • d)
    12 hours and 36 minutes
Correct answer is option 'C'. Can you explain this answer?

Volume of cylinder P = 44 x 14 x 14 x 22/7 = 27104 m3
Radius of cylinder Q = 14 x 3 = 42 m
Height of cylinder Q = (4/11) x 44 = 16 m
Volume of cylinder Q in which the liquid can be filled = 22/7 x 42 x 42 x 16 — 22/7 x 14 x 14 x 16
= 88704 — 9856 = 78848 m3
Time taken to fill cylinder P = 27104/44 = 616 minutes
Time taken to fill cylinder Q = 78848/64 = 1232 minutes
So the time taken to completely fill the 2 cylinders is 1232 minutes or 20 hours and 32 minutes.
