A) \[\left( x+y \right)\]
B) \[\left( x-y \right)\]
C) \[2n=3\]
D) \[\left( x-y \right)\]
Correct Answer: D
Solution :
\[\frac{x\times 5\times 12}{100}=\frac{(8000-x)\times 2\times 18}{100}\] capacity is emptied in 20 minutes So, capacity \[=20\times \frac{6}{5}=24\] \[x=3000\] In 1 min the pipe can empty \[\therefore \] th part. In 9 min the pipe can empty \[9\times \frac{1}{24}\text{th}\]part\[=\frac{3}{8}\text{th}\]partYou need to login to perform this action.
