Step-by-step explanation:

Let the total number of articles be n.

Let the value of one article be a.

Given that trader bought n articles for Rs900.

So that n×a=900 and a=

n

900

Also given that five of them were damaged, he sold the remaining articles for Rs. 2 extra and he also got a Rs. 80 profit.

So that the equation would be (n−5)×(a+2)=900+80

⇒ na−5a+2n−10=980.

⇒ 900−5×

n

900

+2n=990 [∴ na = 900 and a = 900/n]

⇒ 2n−

n

4500

=90

⇒ n−

n

2250

=45

⇒ n

−2250=45n

⇒ n

−45n−2250=0

⇒ n

2

−75n+30n−2250=0

⇒ n(n−75)+30(n−75)=0

⇒ (n−75)(n+30)=0

⇒ n=75 or −30

Since n is the number of goods, it is always positive.

Hence, number of articles he bought was 75.
