Question

5. A P.T. Teacher wants to arrange 6000 students for a drill in such a manner that number of rows is equal to number of columns. How many children would be left out in this arrangement?

Answer 1

Answer:

71

Step-by-step explanation:

$\sqrt{6000}$ = 77.45966.... round off to 77, which is the max number of rows & columns

$77^{2}$=5929, this is the total number of children in the 77 rows and colums

hence number of children left out=6000-5929

                                                       =71
