Question

The square of a positive number is 2000% greater than the number itself then find the square of that number

Answer 1

let the no. be 100x
so its square will be 2000% than itself .....
so it will be.....
=2000*100x/100
=2000x
that is 2000x+100x=2100x
100x*100x=10000x^2
so now 2100x=10000x^2
so it will be...
10000x^2-2100x=0
divide by 100x
100x-21=0
100x=21
X=21/100
so the number is 21/100
I think it is right and helpful for you.....☺
