Question

A group of 120 men had provisions for 200 days .After 5 days, 30men died due to an epidemic. How long will the remaining food last?

Answer 1

answer is:

provision for 120 men of 200 days.

after 5 days,

no of days the provisions for 120 men=200-5=195 days.

but,no. of peoples left=120-30=90 men.

so,let the no. of days the provisions for 90 men be x.

then,by inverse proportion,

=120×195=90×x

=120×195/90=x

=x=260 days.

hence,260 days is the answer.
