Question

5. A garrison of 1000 soldiers have
food for (M.E.) 70 days. After 20 days
200 more soldiers are joined. How
long will the remaining food last ?​

Answer 1

Answer:

41 days

Step-by-step explanation:

1.Given that 1000 soldiers have enough food for 70 days

2.After 20 days the remaining food sufficient for 70-20 days=50days

3., given remaining soldiers in 20 days 1000+200=1200

Then,

Let the remaining food be x

1000/1200 =x/50(by cross multiplication)

1200x=50000

x=50000/1200

x=41.6days

x=41 days

Answer 2

Answer:

Remaining food lasts for $41$ days.

Step-by-step explanation:

We are given that $1000$ soldiers have enough food for $70$ days.

After twenty days the remaining food sufficient for $70-20$ days=$50$ days

After $20$ days $200$ more soldiers are joined $=100+20=120$ soldiers

Assuming the remaining food be $x$

By cross multiplication

$1000/1200 =x/50$

$1200x=50000$

$x=50000/1200$

$x=41.6$ days

Taking as whole number.

$x=41$ days
