Answer: can u pls mark me brainliest pls
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.
