Pipe 'A' can fill a tank in 12 hours. Pipe 'B' is ____% as

Q: Answer-Pipe 'A' can fill a tank in 12 hours. Pipe 'B' is ____% as efficient as pipe 'A'. If both pipes are...

Let the capacity of the tank be 60x litres. So, efficiency of pipe A 60x 12 5x litreshourFor I Efficiency of pipe B 5x 0.50 2.5x litreshour Time taken by both pipes together to fill the tank 60x 2.5x 5x 60x 7.5x 8 hours Therefore, statement I is true.For II Efficiency of pipe B 5x 0.80 4x litreshour Time taken by both pipes together to fill the tank 60x 4x 5x 60x 9x 6.67 hours Therefore, statement II is not true.For III Efficiency of pipe B 5x 1.25 6.25x litreshour Time taken by both pipes together to fill the tank 60x 6.25x 5x 60x 11.25x 5.33 hours. Therefore, statement III is not 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. 50, 8 II. 80, 6 III. 125, 5

A Only I and II

B All I, II and III

C Only I and III

D Only I

E None
