Question

7 horses cab eat 29 kh of food in 8 hours how many more horses would it take to eat total of 20 khs in 4 hours

Answer 1

Explanation:

The first response with the answer as 10 Horses is the correct answer.

Here’s an answer that may (or may not) shed some light:

First, lets figure out how much feed is eaten in a particular day:

500/8 = 62 1/2 kg

So 62 1/2 kg feeds 15 horses each day. Now, we ask, but how much does each horse eats per day?

Well, (62 1/2) / 15 = 4 1/6 kg.

Those information are given but takes a few steps to work out what you need to move forward to solve the problem.

So we know each horse eats 4 1/6 kg per day and we are asked how many horses can it feed in 12 days. In your mind, you should be reasoning, first it was 8 days and it fed 15 horses, now I am increasing the number of days with the same amount of feed, so it should not be able to feed 15 or more horses but less than 15. This helps so if you get an answer 15 or greater, you know it’s incorrect. You may not know the correct answer at this time, but it’s sometimes important to reason in this manner to know when your answer is incorrect.

Final stems:

We know that each horse eats 4 1/6kg per day.

We have to feed as many horses as possible in a 12 day period using the 500kg

SO what will ONE horse eat during this 12 day period? Well, in a day, a horse eats 4 1/6 so in 12 days:

12 x (4 1/6) = 50kg

Now, if a horse will eat 50kg in the 12 day period. How many horses can be fed with 500kg? We know what 1 horse will eat in that period and we know how much feed we have to last, now we figure out how many horses we can feed:

500kg / 50kg = 10 horses

Hope that helps :)
