Multiple choice

Two vessels of capacity 10 litres and 15 litres are filled with a mixture of acid and water. Vessel of capacity 10 litres contains 75% of acid while the other of capacity 15 litres contains 70% of water. The vessels are emptied into a large vessel of capacity 28 litres whose remaining part is filled with acid. Find the ratio of wine and water respectively in the large vessel. 10 लीटर और 15 लीटर क्षमता के दो पात्र अम्ल और पानी के मिश्रण से भरे हुए हैं । 10 लीटर क्षमता वाले पात्र में अम्ल 75% है जबकि 15 लीटर क्षमता वाले पात्र में 70% पानी है। पात्रों को 28 लीटर क्षमता के एक बड़े पात्र में खाली कर दिया जाता है जिसका शेष हिस्सा अम्ल से भर दिया जाता है । बड़े पात्र में क्रमशः अम्ल और पानी का अनुपात ज्ञात कीजिये ।

Explanation

First vessel: 10L with 75% acid = 7.5L acid, 2.5L water. Second vessel: 15L with 70% water = 10.5L water, 4.5L acid. Combined: 12L acid, 13L water. Large vessel capacity is 28L, so remaining 3L is filled with acid, making total acid = 15L. Final ratio acid:water = 15:13. The question asks for wine and water, but this is clearly a typo and should be acid and water.
