Question

In a fort 300 men had provision for 90 days. After 20 days, 50 men left the fort .How long now would the food last at the same rate ? ( PLS DEAR EXPERTS I NEED IT URGENTLY WITH DESCRIPTION I HOPE ALL WILL HELP ME)

Answer 1

After 20 days; 300 men had food for 70 days
suppose 250 boys had food for x days, now less boys more days (indirect proportion)
therefore;
                     250 : 300 :: 70 : x
                     250×x=300×70
                     x=84days..
hope it helps..........
                      

Answer 2

☆Hello friend☆

First 90 days were there but at present days are left 90-20= 70 days

There were 300 men but 50 men then left,

Remaining one's= 300-50= 250 men

So, provision for 300 men= 70 days

Provision for 250 men will be = x

As its indirect variation, so formula

70/x= 250/300

70×300/250= x

2100/25= x

420/5= x

84= x

Hope it helps

Have a ^ Good Day^ Ahead☺
