Answers
Step-by-step explanation:
7. After 12 days, 70 more men joined. Now, 280 men can finish the work in 210×48280 days = 36 days. Hence, it will take 36 days to finish the remaining work.
8. 1200 soldiers in a fort had enough food for 28 days. After 4 days, some soldiers were sent to another fort and thus the food lasted for 32 more days. ... The number of soldiers who were sent to another fort lasted for 4 days in this fort. So the number of days left for enough food = (28 – 4) = 24 days.
