Water flowing with chlorine concentration 10 mg/L at the rate of 20 Li

1.	Water flowing with chlorine concentration 10 mg/L at the rate of 20 Liter/min, is discharged into a river if the concentration of chlorine in a river is 5 mg/L what is the flow rate of river?(a) 10 Liter/min(b) 20 Liter/min(c) 30 Liter/min(d) 40 Liter/minI got this question during a job interview.I would like to ask this question from Multiple Component Systems topic in section Introduction to Material Balances of Basic Chemical Engineering
Answer» The correct OPTION is (a) 10 Liter/min Explanation: Rate of FLOW of river = 20*5/10 = 10 Liter/min.
