Question

there is enough foodstuff for 1200 army personnel of a camp for 40 days. 400 more personnel came to the camp. For how many days will be foodstaff be enough now

Answer 1

Answer:

30days

Step-by-step explanation:

given that

there is enough food for 200 army personnel of a camp 40 days

if 400 more personal came to our camp then 1200+400=1600

here if X1,X2 are the number of personnel's came to the camp then X1=1200andX2=1600

if Y1,Y2 are the number of days for the enough food stuff to the personnels of the camp then Y1=40,Y2=x

the formula is X1/X2=Y2/Y1 from the chapter direcl and inverse proportion,then

Y2= X1×Y2/X2,that is

x=1200×40/1600

x= 1200×40=48000

x=48000/1600=30

so, if 400 more personals join the camp the foodstuff is enough for 30 days
