Dear Student,

Food lasts for 200 days for 120 people

After 5 Days
food lasts for (200-5) days for 120 people

But when 30 people die

food lasts for
 120×(200-5)120-30=120×19590=4×65=260 days
for rest of the 90 people.

men            days
120              20
90               x
after 5 days=120-30=90
we do, 120*90=200*x       formula(x1/y1=x2/y2)
=108/2   = 54
thats your answer = 54 days
