many soldiers join?
Answers
Answer:
So after 13 days they would have used the standard provisions only after that would the new soldiers affect the provisions! At this point they have 48 - 13 = 35 days
however the provisions are used in 25 days which means there are extra people - how many? Here goes
35/25 = 1,4 x 1500 = 2100 soldiers
2100 - 1500 = 600 soldiers joined
Answer:
600 soldiers
Step-by-step explanation:
Given:
Numbers of soldiers in a fort have provision = 1500
Days food last when there were 1500 = 48days
After 13 days few soldiers joined (let it be x)
Food lasts for when there were 1500 + x =25 days
Now,
If, in one day one soldier eats 1 food item
Then, in one day 1500 soldiers eat 1500 food items.
Now, in 48 days no. of food items eaten = 1500 × 48 = 72000 food items
If x soldiers joined after 13 days.
So, the food items eaten by 1500 + x soldiers = 1500 (48 - 13) = 1500 × 35
= 52500 food items
Now, 52500 lasts for 25 days
∴ 52500 = 25 (1500 + x)
⇒ 52500 = 37500 + 25x
⇒ 25x = 52500 - 37500
⇒ x = 15000/25
⇒ x = 600 soldiers
