Rahul purchased an article for Rs. 8400 and sold it for a loss of 5%. ...
Given, cost price of first article = Rs. 8400
Loss incurred on selling the article = 5%
Selling price of the first article = Cost price - Loss = 8400 - (5/100) * 8400 = Rs. 7980
Using the money obtained from selling the first article, Rahul purchased another article and sold it for a gain of 5%.
Let's calculate the cost price of the second article using the selling price of the first article.
Selling price of the first article = Cost price of the second article
Selling price of the second article = Cost price of the second article + 5% of cost price of the second article
Using the above two equations, we can write:
Cost price of the second article = Selling price of the first article
= Rs. 7980
Selling price of the second article = Cost price of the second article + 5% of cost price of the second article
= 7980 + (5/100) * 7980
= Rs. 8379
Now, let's calculate the overall gain or loss.
Overall profit or loss = Selling price of the second article - Cost price of the first article
= 8379 - 8400
= -21
Since the overall value is negative, it means that Rahul has incurred a loss of Rs. 21. Therefore, option (c) is the correct answer.
