Question

1200 soldiers in a fort had enough food for 28 days.After 4 days,some soidiers were transferred to another fort and thus the food lasted for 32 days.How many soldiers left the fort?​

Answer 1

Answer:

Proportional method

As the number of soldiers increases, the number of days the food lasts, will decrease. So number N of soldiers is inversely proportional to the number D of days. Hence, there were only 900 soldier after 4 days. So 1200 - 900 = 300 soldiers are transferred.

Answer 2

Answer:

Given that 1200 soldiers in a fort had enough food for 28 days

Let the number of soldiers transferred to another fort be x

After 4 days, number of soldiers = (1200 – x)

Given that food lasted for 32 more days.

Hence 1200 × 24 = (1200 – x) × 32

⇒ (1200 – x) = 900

⇒ x = 1200 – 900 = 300

Thus 300 soldiers were transferred to another fort.
