Question

a stable has enough food for 20 horses for 15 days. however some horses were sold and the food lasted for 25 days .How many horses were sold ?​

Answer 1

Answer:

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.
