How much water should be added to 60 liters of milk costing \(1\frac{1}{2}\) per liter at ₹ 20 to get a mixture costing ₹\(10\frac{2}{3}\) per liter?
20₹ में \(1\frac{1}{2}\) लीटर कीमत वाले 60 लीटर दूध में कितना पानी मिलाया जाना चाहिए कि ₹ \(10\frac{2}{3}\) प्रति लीटर कीमत का मिश्रण प्राप्त हो?
Detailed Solution & Logic
Correct Answer:
15 liter
Cost of 60 L milk = $ 60 \times \frac{40}{3} = 800 $
Let water added = $ x \text{ L} $
\(\frac{800}{60 + x} = \frac{32}{3}\)
$ 60 + x = \frac{800 \times 3}{32} = 75 $
x = 75 - 60 = 15
Answer = 15 L
