P.S.Want 1 answer done by proportional method and the other in unitary meKippthod.

Answer 1

up1200 soldiers ..... 28 days

Let every soldiers eat every day =1 kg

total food is 1200×28 = 33600 kg

food eaten by 1200 S in 4 days = 1200×4=4800


food left = 33600-4800= 28800

Let number of soldiers left in Camp = X

ATQ

X× 32= 28800

X= 900


So number of people transferred to another camp is 1200- 900= 300

$ans - 3000$
