Question
Download Solution PDFदूध और पानी के मिश्रण से सूर्य के प्रकाश में पानी के वाष्पीकरण की दर 2.5 लीटर / घंटा है। सुबह 10:00 बजे दूध की मात्रा पानी की तुलना में 90 लीटर अधिक थी और उसी दिन शाम 4:00 बजे, दूध का पानी से अनुपात 8: 1 हो जाता है, तो उसी दिन 8:00 बजे मिश्रण की कुल मात्रा में दूध प्रतिशत कितना होगा ? (मान लीजिये सूर्य का प्रकाश रात्रि 8:00 बजे तक है)
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFसुबह 10:00 बजे दूध और पानी की मात्रा 'x + 90' और 'x' है।
पानी की मात्रा सुबह 10:00 बजे से शाम 4:00 बजे तक = 2.5 × 6 = 15 लीटर
प्रश्न के अनुसार:
\(\frac{{x + 90}}{{x - 15}} = \frac{8}{1}\)
x + 90 = 8x – 120
7x = 210
x = 30
रात 8:00 बजे दूध की मात्रा = (x + 90) = 120 लीटर
रात 8:00 बजे पानी की मात्रा = x – 2.5 × 10 = 30 – 25 = 5 लीटर
आवश्यक प्रतिशत = (120/125) × 100 = 96%
