🔷 An 8 litres cylinder contains a mixture of oxygen and nitrogen, the volume of oxygen being 16% of total volume. A few litres of the mixture is released and an equal amount of nitrogen is added. Then the same amount of the mixture as before is released and replaced by nitrogen for the second time. As a result, the oxygen content becomes 9% of the total volume.How many litres of mixture is released each time?
(1)1 (2)2 (3)3 (4)4 (5)5 ═══════════════════ 🔷 9 litres are drawn from a cask of full water and it is then filled with milk. 9 litres of mixture are drwan and the cask is again filled with milk. The quantity of water now left in the cask is to that of the milk in it as 16 : 9. How much does the cask hold? (1)36 litres (2)27 litres (3)45 litres (4)54 litres (5)None of these ═══════════════════
