• B.
• C.
• D.

Answer 1

The correct option is C

Say:
Kino is making a picture table for the number of animals in his father’s farm.
- The number of goats is 1 more than the number of cows.
- There are 2 fewer cows than the number of chickens.
- The number of chickens is 4 more than the number of horses.
- The number of pigs is 1 more than the number of horses.
- There is 1 horse on the farm.

Steps:
- Let us make a table on the board.
- We will begin with what we know, i.e. there is 1 horse.
- Since we know the number of horses, we can find the number of pigs.
- It is 1 more than the number of horses, i.e., 1 + 1 = 2.
- Thus, there are 2 pigs.
- Since we know the number of horses, we can also find the number of chickens.
- It is 4 more than the number of horses, i.e., 1 + 4 = 5.
- Thus, there are 5 chickens.
- Since we know the number of chickens, we can find the number of cows.
- It is 2 less than the number of chickens, i.e., 5 - 2 = 3.
- Thus, there are 3 cows.
- Since we know the number of cows, we can find the number of goats.
- It is 1 more than the number of goats, i.e., 1 + 3 = 4.
- Thus, there are 4 goats.
- Thus, to summarize: The number of goats = 4, cows = 3, chickens = 5, horses = 1, pigs = 2.
- The picture table that has these numbers of animals is of option C.
- Hence, option C is the answer.
