Answer:
(a) Since, the remaining days\[=\left( 9020 \right)\] days = 70 days But remaining number of men \[=\text{ }30050\] = 250 Let the number of days = x, then
Clearly less men will have food for more days. Then, by inverse variation, \[\frac{300}{250}=\frac{x}{70}\] \[x=\frac{70\times 300}{250}\] \[x=\frac{70\times 6}{5}\] \[x=14\times 6\] = 84 Hence, the number of days = 84. Number of men 300 250 Number of days 70 x
