Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFपुरुषाचे 1 दिवसाचे काम = 1/3
स्त्रीचे 1 दिवसाचे काम = 1/5
मुलाचे 1 दिवसाचे काम = 1/15
प्रश्नानुसार-
⇒ 1 × (1/3) + 1 × (1/5) + x × (1/15) = 1/(1/5)
{∵ x आवश्यक असलेल्या मुलांची संख्या}
⇒ x/15 = 5 - (1/3) - (1/5)
⇒ x/15 = (75 - 5 - 3)/15
⇒ x = 67
∴ काम पूर्ण करण्यासाठी 67 मुलांची मदत घ्यावी लागेल.
