A person mixes two liquids, x and y . One litre of x weighs approximately 900 g, and one litre of y weighs approximately 750 g . If one litre of the mixture weighs approximately 800 g, then the percentage of x in the mixture is:

Solution & Step-by-step Explanation

Using the rule of allegation:Weight of 1 litre of x = 900 g Weight of 1 litre of y = 750 g Mean weight of mixture = 800 g $ Liquid x 900 (800 - 750) = 50 ↘ ↙ 800 ↙ ↘ Liquid y 750 (900 - 800) = 100 R a t i oo f x : y = 50 : 100 = 1 : 2 . P erce n t a g eo f x in t h e mi x t u re : Percentage of x = \frac{1}{1 + 2} \times 100 = \frac{1}{3} \times 100 = 33 \frac{1}{3} % $
