alleryजर 12 कामगार एक काम 8 दिवसांत पूर्ण करू शकतात, तर 16 कामगार ते काम किती दिवसांत पूर्ण करतील:
A4 दिवस
B6 दिवस
C9 दिवस
D10 दिवस
Answer & Solution
Correct answer: B. 6 दिवस
1. एकूण काम 12 x 8 = 96 कामगार-दिवस आहे.
2. कामगारांची संख्या बदलली तरी हे एकूण काम बदलत नाही.
3. 16 कामगारांसह लागणारा वेळ 96 / 16 आहे.
4. म्हणजेच 6 दिवस.
5. जास्त कामगार म्हणजे कमी दिवस, त्यामुळे उत्तर 8 पेक्षा कमी असले पाहिजे, ज्यावरून 9 आणि 10 हे पर्याय बाद होतात.
