Answer 2

Answer:

let the total no of aarticles be n

let the value of one article ne a

given:

        na=900

       a=900/n

(n-5)*(a+2)=980

na-5a+2n=990

900-5(900/n)+2n=990

2n-4500/n=90

n2-2250=45n

n2-45-2250=0

n(n-75)30(n-75)

(n+30)  (n-75)

n=-30  n=75

sine the no of arrticles cannot be in negative

the answer is 75
