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.

@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.

If men decrease then no of days food last will increases for eg: men is halved then days will be doubled.
Similarly, 125 is 5/6th of 150.
So 6/5th of 35 is 42 days.

In the start, total food (150*45).
1-10 days used food (10*150).
After 10 days remaining food (125*y).
So (150*45) = (150*10) + (125*y).
y = 42.

A ship has food provision for 300 people for 30 days. If 200 more people join the ship, how long will the provisional last?
Can anyone solve this?

It means that for 35 days 150 men have enough food.
So 25 leave.
Now the question is how many days will the remaining food be enough for 125 men.
So 25 leave.
Now the question is how many days will the remaining food be enough for 125 men.

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