ANSWER
Let the no. of articles bought by the trader be x.
Total cost price = Rs. 1200
∴ CP of 1 article =
x
1200
10 articles were damaged, so remaining articles =(x−10)
New CP of 1 article = Rs.
x−10
1200
SP of 1 article = Rs. (
x−10
1200
+2)
Profit on entire transaction = Rs. 60
Now for 1 article, Profit = S.P - C.P
∴
x−10
60
=
x−10
1200
+2−
x
1200
∴ x=100
