Question

1000 soldiers in a fort had enough food for 20 days. But some soldiers were transferred to another fort so the food lasted for 25 days. How many soldiers were transferred.

Answer 1

Let the number of soldiers transferred be = x
by unitary method
number of soldiers   days food lasted   
1000                             20
1000-x                          25
by inverse variation  

1000 × 20 = (1000-x) × 25

1000 ×20/ 25 =1000 - x

800 = 1000 -x

x= 1000 - 800

  = 200
∴ 200 soldiers were transferred to another fort.
