Multiple Choice Question
A and B can do a piece of work in 12 days, B and C in 15 days, and C and A in 20 days. How long would A alone take to do the same work?A और B एक काम को 12 दिनों में, B और C 15 दिनों में, तथा C और A 20 दिनों में पूरा कर सकते हैं। A अकेला उसी काम को कितने दिनों में पूरा करेगा?
Explanation:
Total Work = LCM(12,15,20) = 60. Efficiency: A+B=5, B+C=4, C+A=3. Sum = 2(A+B+C) = 12 => A+B+C = 6. A's eff = 6 - (B+C) = 6 - 4 = 2. Time for A = 60/2 = 30 days.
कुल कार्य = 60। (A+B+C) की क्षमता = 6। A की क्षमता = 6 - 4 = 2। A को लगा समय = 60/2 = 30 दिन।
