Question

a garrison of 120 men has provision for 30 days at thr end of five days five more men jointed them how many days can they sustain on the remaining provision ​

Answer 1

hey mate ^_^

=============================

we know that no. of days is inversely propotional to the provision for men. 

So for 120 men the provision would last for 30days. (given) 

Therefore, the provision for 1 men would sustain for. 120 *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 

A.t.q 120*30 = 120*5+125*x 

(120*30) - (120*5)= 125x 

120(30-5)=125x 

120 * 25 = 125x 

120 = 5x 

x=120/5 

x= 24 

so the provision would remain for more 24 days.

hope it helps : )
