there are 600 children in a school for PT drill they have to stand in such a way that number of rows is equal to the number of column

we have to find that how many children should be left in this arrangement

so according to the question the number which should be subtracted from 600 to make it a perfect square has to be calculated

the square root of 600 can be calculated by long division method

2| 600| 24

-4

44|200 |

-176

24

so the reminder is 24

the square of 24 is less than 600

therefore if we subtract 24 from 600 and we get 600 - 24 = 576..

Is that your answer...
