Question

9. 1,200 soldiers in a fort had enough food for 28 days. After 4 đàys, some soldiers were<br />transferred to another fort and thus the food lasted now for 32 days. How many soldiers<br />left the fort?<br />​

Answer 1

Answer:

1050

Step-by-step explanation:

1200*28=(1200-x)*32

1200*28/32=1200-x

150*7=1200-x

1050-1200=-x

-150=-x

x=150
