Question

In a barrack of soldiers there was stock of food for 190 days for 4000 soldiers. After 30 days, 800 soldiers left the barrack. For how many days shall the left over food last for the remaining soldiers?

Answer 1

Answer:

Left over food last for 200 days for remaining soldiers.

Step-by-step explanation:

No of days food last for 4000 soldiers = 190

No of soldiers left after 30 days = 4000 - 800 = 3200

Let say Quantity of food = 190 × 4000 = 760000

Quantity of food consumed by 4000 soldiers in 30 days = 30 × 4000 = 120000

Quantity of food left = 760000 - 120000 = 640000

No of day food last = $\frac{640000}{3200}=200$

Therefore, Left over food last for 200 days for remaining soldiers.

Answer 2

Question :- In a flood releif camp, there is provision for 4000 persons for 190 days . After 30 days 800 person shifted to a different place. Find, how long will the remaining food be served to the remaining persons ?

Solution :-

we know that,

• M1 * D1 = M2 * D2

given that,

• M1 = 4000 persons .
• D1 = Days left = 190 - 30 = 160 days.
• M2 = Person left = 4000 - 800 = 3200 persons .
• D2 = Let x days.

then, putting all values we get,

→ 4000 * 160 = 3200 * x

→ 4000 = 20x

→ x = 200 days. (Ans.)

Hence, the remaining food be served to the remaining persons for 200 days.
