Ratio of milk to water in a jar is 5:1. If 10 litres of this mixture is removed and 4 litres of milk and 2 litres of water are added, then quantity of milk becomes 300% more than that of water in the jar. What was the original quantity of water in the jar?
I tried in the following manner and have doubt.
There are three ratios here 5:1, 2:1 (Added 4 litres milk and 2 litres water) and 4:1 (300% more) If we take LCM, then ratio becomes 25:5, 20:10 and 24:6. If we add the first two ratios then we should get the third ratio right. Whether am I wrong?
Let $x$ be a quantity of a water in the jar.
Thus, $$5x-\frac{5}{6}\cdot10+4=4\left(x-\frac{1}{6}\cdot10+2\right).$$ Can you end it now?
