Question

There are 4931 children in a school. For a PT drill they have to stand in such a way that the number of rows is equal to number of columns How many children would be left out in this arrangement... Please give in detail...

Answer 1

Answer:

as the no.of rows is equal to the no. of column

then the no of student

required is a perfect square no.

nearest no. of 4931 which is a perfect square is 4900

so,the no. of student left is 4931-4900=31

Answer 2

if the number of rows and columns is same then obviously we have to know the square root of 4931 other wise nearly other number ..so the number I got 4900 .. that's square root is 70 and there would be left 31 bcZ 4931-4900=31
