Verified Answer
After selling70% of the articles on 40% discount shopkeeper announces ...
Without losing generality we can assume that shopkeeper has 100 articles with marked price of 100.
Now, for first 70 articles he offered discount of Rs. 40 on each of the articles.
Hence selling price of these 70 articles will be Rs. 60 each.
∴ Total selling price of these 70 articles will be,
70 x 60 = 4200
And he offers additional 30% discount on remaining articles.
Hence selling price of these 30 articles will be 70% of 60 i.e. Rs. 42 each.
∴ Total selling price of these 30 articles will be,
30 x 42 = 1260
Total selling price of 100 articles is,
1260 + 4200 = 5460
This is 20% more than cost price. Hence,



Hence, option 1.
