Question

there are 500 childern in a school. for a P.T. drill they have to stand in such a manner that the no. if rows and columns are equal how much childern will be left out of these arangement​

Answer 1

Answer:

Step-by-step explanation:

Let the numbers of rows and columns be x.

By prime factorisation,

500 = 2*2*5*5*5

After pairing the numbers,

5 will be left as unpaired.

Therefore, 5 children will be left out of these arrangement.

Hence, x*x = 2*2*5*5

=> x^2 = 100

=> x = √100

=> x = 10

Answer 2

hii..

i think 16 children will be left out of these arrangment..
