Question

In a rally 841 cadets participated. The officer asked them to stand in rows in such a manner, the number of cadets in each row equals the number of rows. How many cadets were there in each row?

Answer 1

Answer:

29

Step-by-step explanation:

841 to be divided in equal amount of rows and columns =>

If there are x cadets in rows, x cadets will be in columns as well

=> x*x = 841 => x =√ 841 = 29

Answer 2

Given:

Number of cadets=841

To find:

The number of cadets in each row

Solution:

The required number of cadets is 29.

We can find the number by following the given steps-

We know that the total cadets in every row have to be the same as the total rows.

So, the total cadets in a row=number of rows.

We know that the total cadets are the product of the total rows and cadets in every row.

Total number of cadets=Number of cadets in every row× number of rows

We are given that there are 841 cadets in total.

Let us assume that the cadets in each row are A.

So, the total rows are also equal to A.

Total number of cadets=A×A

841=$A^{2}$

$\sqrt{841}$=A

29=A

Therefore, the required number of cadets is 29.
