Question

A factory has a food for 70 persons for 20 days.After 10 days ,15 members leaves the factory and 7 members join the company. Then for how long the food lasts.....​

Answer 1

Given that Total men = 210 and they had provisions for 60 days.

Therefore the total available food = 210 * 60

= 12600

Given that After 10 days, 60 men left.

Then the food consumed for 10 days = 210 * 10

= 2100.

Now, the available food = 12600 - 2100

= 10500.

Remaining men = 210 - 60

= 150.

Therefore the remaining food lasts for 10500/150 = 70 days.

Answer 2

Answer:

Given that total men=210 and they had

provisions for 60 days

Therefore the total available food=210*60

=12600

Given that After 10 days, 60 men left.

Then the food consumed for 10 days=210*10

=2100

Now, the available food=12600-2100=10500

Remaining men=210-60=150

Therefore the remaining food lasts for 10500/150=70 days
