Pipe 'A' can fill a tank in 20 hours. Pipe 'B' is ____% as

Q: Answer-Pipe 'A' can fill a tank in 20 hours. Pipe 'B' is ____% as efficient as pipe 'A'. If both pipes are...

Let the capacity of the tank be 100x litres. So, efficiency of pipe A 100x 20 5x litreshourFor I Efficiency of pipe B 5x 0.25 1.25x litreshour Time taken by both pipes together to fill the tank 100x 1.25x 5x 100x 6.25x 16 hours Therefore, statement I is true.For II Efficiency of pipe B 5x 1.00 5x litreshour Time taken by both pipes together to fill the tank 100x 5x 5x 100x 10x 10 hours Therefore, statement II is true.For III Efficiency of pipe B 5x 1.50 7.5x litreshour Time taken by both pipes together to fill the tank 100x 7.5x 5x 100x 12.5x 8 hours Therefore, statement III is true.

efficient as pipe 'A'. If both pipes are opened simultaneously, the tank will be completely full in ____hours.The values given in which of the following options will fill the blanks in the same order in which is it given to make the statement true: I. 25, 16 II. 100, 10 III. 150, 8

A Only I and II

B All I, II and III

C Only I and III

D Only III

E None
