A and B together can complete a job in 8 days. If A alone can do it in 16 days, how many days will B alone take?
16 days
10 days
12 days
14 days
Answer: A
Combined work rate = 1/8 per day and A's work rate = 1/16 per day. B's rate = 1/8 - 1/16 = 1/16. Therefore, B alone takes 16 days.
A और B मिलकर एक काम 8 दिनों में पूरा कर सकते हैं। यदि A अकेले इसे 16 दिनों में पूरा कर सकता है, तो B अकेले इसे कितने दिन में पूरा करेगा?
16 दिन
10 दिन
12 दिन
14 दिन
उत्तर: A
दोनों की संयुक्त कार्य-दर = 1/8 प्रतिदिन और A की कार्य-दर = 1/16 प्रतिदिन। B की कार्य-दर = 1/8 - 1/16 = 1/16। अतः B अकेले काम 16 दिनों में पूरा करेगा।
