Question
A $90$-litre mixture has milk and water in the ratio $4:5$. How much milk must be added to make the ratio $2:1$? / $90$ लीटर के मिश्रण में दूध और पानी $4:5$ के अनुपात में हैं। अनुपात $2:1$ बनाने के लिए कितना दूध मिलाना होगा?
Option 4 : $60$ litres / $60$ लीटर
Detailed Solution
सही उत्तर $60$ litres / $60$ लीटर है।
Milk $= 40$ litres, water $= 50$ litres. For ratio 2:1, milk must be $2 \times 50 = 100$ litres, so add $100 - 40 = 60$ litres. / दूध $= 40$ लीटर, पानी $= 50$ लीटर। 2:1 अनुपात के लिए दूध $2 \times 50 = 100$ लीटर होना चाहिए, अतः $100 - 40 = 60$ लीटर मिलाना होगा।
