Question

The number of students in school A is 5 more than two times the number of students in school B. The product of the number of students in both the schools is 81000. What is the number of students in school A?
​

Answer 1

5x:2x=81000

5-2=81000

3x=81000

x=81000/3=27000 in school A

Answer 2

Answer:

Product of the number of students in both classes=81000 students.

let no.of students in class B=x.

therefore,no. of students in class A=(x×2)+5.

{(X×2)+5}×{X}=81000

=>{2X+5}×X=81000

=>2X^2+5X=81000

=>2X^2+X=81000/5

=>2X^2+X=16200

=>X^2+X=16200/2

=>X^2+X=8100

=>X^2+X=(90)^2

=>X+X=90

=>2X=90

=>X=90/2

=>X=45
