Question

1200 soldiers in a Fort had enough food for 28 days after four days some soldiers were transferred to another for and thus the food lasted now for 32 more days how many soldiers left the Fort

Answer 1

inverse variation
let no of soldiers be x
let no of days be y
x=k
y
xy=k
x=1200,y=28
xy=k
1200×28=k
33600=k
x=?,y=32,k=33600
xy=k
32x=33600
x=33600
32
x=140
soldiers left the fort =140
