एक माणूस एक काम 8 दिवसात पूर्ण करतो आणि त्याचा मुलगा तेच काम 24 दिवसात पूर्ण करतो. जर त्या दोघांनी एकत्र काम केले तर त्यांना काम पूर्ण करण्यास किती दिवस लागतील ?

The correct answer is Option B (6 days).

Key Points:
• The key concept is combining work rates (Time and Work).
• Man's 1-day work = 1/8.
• Son's 1-day work = 1/24.
• When they work together, their combined 1-day work is the sum of their individual rates.
• Combined 1-day work = 1/8 + 1/24.
• Take the LCM of 8 and 24, which is 24. = 3/24 + 1/24 = 4/24 = 1/6.
• Since their combined rate is 1/6 of the work per day, it will take them exactly 6 days to finish the work.
• Shortcut formula: (A × B) / (A + B) = (8 × 24) / (8 + 24) = 192 / 32 = 6 days.
• Key Takeaway: To find combined time for two workers A and B, use the direct formula: (A × B) / (A + B).
