My kid is practicing word problem. I have an issue with the question which i m unable to produce any solution. Would be appreciated if any solution is provided.

QUESTION:

In the village there were four different types of animals: pigs, sheep, chickens & cows.

• Every fourth animal was a pig
• One out of eight animals was a sheep
• Half of the animals were chickens
• The rest of the animals were cows. There were 50 cows.

How many animals of each type were there in the village?

• You could find the total number of animals first. – David Mitra May 5 at 10:07
• @DavidMitra thanks for the suggestion. Thats what i am am thinking about but i am confused how should i do that. I feel it like a series calculation. But not sure how should i do it. – Muhammad Umair Shafique May 5 at 10:08
• Call the total $T$. Express the number of each animal in terms of $T$ (e.g., the number of pigs is $T/4$). Then make an equation... – David Mitra May 5 at 10:13

If we have 8 animals

• pigs are 2
• sheep is 1
• chickens 4
• cow is 1

So for 50 cows we multiply by 8 = 400 animals

• pigs are 100
• sheeps are 50
• chickens are 200
• cows are 50
