A fort had provision of food for 150 men for 45 days. After 10 days, 25 men left the fort. The number of days for which the remaining food will last, is:
Answer: Option
Explanation:
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 = |
150 x 35 |
| 125 |
x = 42.

Let the required number of days be 'x'.
150*45=(150*10)+(125*x),
Hence, x=42.
150*45=(150*10)+(125*x),
Hence, x=42.

25 persons food remain for next 35 days.
125 person can eat the above food fro next 7 days.
ie 25*35/125=7.
so 35 days + 7 days=42 days.

Let the total food be x.
150 men ate x food for 45 days i.e. 150 men ate x food for first 10 days and rest 35 days
But when 25 men left after 10 days the food left was only what 150 men would eat for the rest 35 days as mentioned above.
Hence 125 men only had food that 150 men would have eaten for rest 35 days.
Thus,
150:125= days:35 ( inversely proportionate)
Days = 150*35/125=42.
150 men ate x food for 45 days i.e. 150 men ate x food for first 10 days and rest 35 days
But when 25 men left after 10 days the food left was only what 150 men would eat for the rest 35 days as mentioned above.
Hence 125 men only had food that 150 men would have eaten for rest 35 days.
Thus,
150:125= days:35 ( inversely proportionate)
Days = 150*35/125=42.

@Sameenamhd.
Your question is an inversely proportionate one without any condition.
If 9 people eat for 26 days.
Then 13(9+4) will eat for x.
9:13=x:26 then x=18 days.

@Vikas.
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?
