Question

There were $500$ soldiers in a fort. They had enough food for $30days$ but $125$ soldiers were transferred to another fort. For how many days did the food last now?

Answer 1

Step 1: Find the number of soldiers

Total numbers of soldiers in the fort = $500$

Number of soldiers transferred = $125$

Number of soldiers left after transfer =$500-125=375$

Step 2: Find Number of days

$500$ soldiers had for $30days$

$1$ soldiers had for $30\times 500=15000days$ (less soldiers, more days)

$375$ soldiers had for $\frac{15000}{375}=40days$ (more soldiers, less days)

Hence, the food last for $40days$.
