Three pipes A, B and C can fill a tank from empty to full in 30 minutes, 20 minutes, and 10 minutes respectively. When the tank is empty, all the three pipes are opened. A, B and C discharge chemical solutions P,Q and R respectively. What is the proportion of the solution R in the liquid in the tank after 3 minutes?

✅ Correct Answer: 6/(11)

Explanation

Part filled by(A+B+C)in 3 minutes=3 1/(30)+Part filled by C in 3 minutes=3/(10)[https://www.indiabix.com/_files/images/aptitude/1-sym-tfr.gif] Required ratio=3/(10)x
