Question
There is 160 litres of mixture of milk and water in a
jar. The ratio of quantity of milk to water in the jar is 5:3, respectively. If lsquo;xrsquo; litres of mixture is taken out from the jar then the difference between quantity of milk and water left in the jar is 30 litres. Find the value of lsquo;xrsquo;Solution
Let the quantity of milk and water left in the jar be 5a litres and 3a litres, respectively According to the question, 5a ndash; 3a = 30 =gt; a = 15 Therefore, quantity of mixture left in the jar = 5a + 3a = 8a = 120 litres Therefore, quantity of mixture taken out = 160 ndash; 120 = 40 litres =gt; x = 40
