Question
A and B together can complete a task in $8$ days, while A alone takes $12$ days. How long will B alone take to complete the task? / A और B मिलकर किसी कार्य को $8$ दिनों में पूरा कर सकते हैं, जबकि A अकेला $12$ दिन लेता है। B अकेला कार्य पूरा करने में कितना समय लेगा?
Option 4 : $24$ days / $24$ दिन
Detailed Solution
सही उत्तर $24$ days / $24$ दिन है।
B's rate $= \frac{1}{8} - \frac{1}{12} = \frac{1}{24}$, so B alone takes $24$ days. / B की दर $= \frac{1}{8} - \frac{1}{12} = \frac{1}{24}$, इसलिए B अकेला $24$ दिन लेगा।
