Answer :

We know that no. of days is inversely proportional to the provision for men.


Given:


For 120 men the provision would last for 30days.


The provision for 1 men would sustain for. 120 x 30 = 3600 days.


Let after the joining of 5 men (after 5 days) the no of more days the provision would last is x days


Now according to the question


120 × 30 = 120 × 5 + 125 × x


3600 – 600 = 125x


3000 = 125x



So, the provision would remain for more 24 days.
