After 10 days : 150 men had food for 35 days.
Suppose 125 men had food for x days.
Now, Less men, More days (Indirect Proportion)
125 : 150 :: 35 : x 
125 x x = 150 x 35
 x = |

@Liza.
1 student has provision for 150 x 45 days.
125 students have provision for 150 x 45 / 125 = 54 days.
1 student has provision for 150 x 45 days.
125 students have provision for 150 x 45 / 125 = 54 days.

What if the question had been how many more days the food lasts? Then would the answer be 42-35 = 7 more days.

@Pushpak.
I guess 1430 men came after 17 days,
2200*33 = (2200+x) * 20.

Could you explain this sum for me, please. In a fort, there was sufficient food for 24 weeks for 200 soldiers. 80 more soldiers join the group at the end of one week and quantity of food served to each soldier was reduced from 900 gm to 750 gm. For how many days the rest food would last now?
