Question

A group of 210 men had provisions for 60 days. After 10 days,60 men left . How long will the remainig food last?

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.


Hope this helps!

Answer 2

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.

Hope this helps!
