के लिए, 31 दिनों तक के लिए पर्याप्त भोजन है. 28
दिनों के बाद 280 व्यक्ति, उस जगह को छोड़
कर चले गए. बताइए कि शेष भोजन, शेष व्यक्तियों के लिए कितने दिनों तक चलेगा?]
(a)
6 days (b) 7 days (c) 10 days (d) 15 days (e) None of these
Detailed explanation:
The food is sufficient is for 400 men for 31 days. After 28 days, 280 men leave the place.
So, 400 - 280 = 120 men remains; where as the remaining time is just 3 days.
Since the rest food is sufficient for 400 men for 3 days
Therefore, it will be sufficient for remaining 120 for (400/120) * 3 = 10 days Ans.
So, 400 - 280 = 120 men remains; where as the remaining time is just 3 days.
Since the rest food is sufficient for 400 men for 3 days
Therefore, it will be sufficient for remaining 120 for (400/120) * 3 = 10 days Ans.
