Question

An army general arranges his soldiers in such a way that the rows is same as the number of columns.In such an arrangement 55 soldiers are left behind.If the total number of students are 6455.Find the number of soldiers in each row

Answer 1

the total number of soldiers in the arrangement is (no. of rows)*(no. of columns)
and the remaining soldiers+the soldiers in this formation=6455(given)..
the equation according to the problem is:
x^2+55=6455 (where x is the no. of rows..)
so, x^2=6400
x=80 is the required answer..

Answer 2

Answer:

Total number of soldiers=6455

Number of soldiers left out =55

Let the number of rows =x

Let the number of columns =x

Number of soldiers remained=6455−55

=6400

Now,

x2 =6400

=>x= √6400

=>x=80

Number of columns and number of rows =80
