Question

Sean places 28 tomato plants in row's . All rows contain the same number of plants .There are between 5 and 12 plants in each row. How many plants are in each row?

Answer 1

The correct answer is:

7 plants in each row.

Explanation:

To answer this, we must find the factors of 28:

1 and 28; 2 and 14; 4 and 7.

Out of these, the only factor that is between 5 and 12 is 7. This means there are 7 plants in each row.

Answer 2

There are 7 plants in each row.

Given Conditions are as follows

1. Sean places 28 tomato plants in rows

2. All rows contain the same number of plants

3. There are between 5 and 12 plants in each row.

so our answer must satisfy all the given conditions

From the second condition we can conclude that the rows contain equal number of plants and hence

We can only take pairs which make multiples of 28. These are

{ Rows , Columns}  

Also , The product of Rows and Columns must be 28.

So we can write

(1) {28 ,1 }

(2) { 14, 2}

(3) { 7 , 4}  

But according to Third Condition

There are between 5 and 12 plants in each Row.

So only one pair , Pair 3 viz  (7, 4} satisfies All  Conditions.

hence we can conclude that there are 7 plants in each row.
