Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 682

Given:

A sold an article to B at 24% profit.

B sold it to C at 30% profit.

B's profit was Rs. 72.60 more than that of A

Formula used:

Profit = Selling price - Cost price

Calculations:

Let the cost price of the article A be 100x

Selling price of A = Cost price of B = 124% of 100x = 124x

Profit of A = 124x - 100x = 24x

Selling price of B = 130% of 124x = 161.2x

Profit of B = 161.2x - 124x = 37.2x

Difference in profits of A and B = 37.2x - 24x = 13.2x

According to the question;

⇒ 13.2x = 72.6

⇒ x = 5.5

Cost price of B = 124x = 124 × 5.5 = Rs 682
