The cash difference between the selling prices of an article at a profit of 4% and 6% is Rs. 3. The ratio of the two selling prices is:__________?
Correct answer: B. 52:53
- A. 51:52
- B. 52:53
- C. 51:53
- D. 52:55
Explanation
The difference between the selling prices is the difference in profit, which is 6% - 4% = 2% of the cost price. Thus, 2% of cost price = 3 Rs, giving cost price = 3 Rs / 0.02 = 150 Rs. The selling prices are 1.04 x 150 Rs = 156 Rs and 1.06 x 150 Rs = 159 Rs, so their ratio is 156:159 = 52:53. The common mistake is using the profit percentages as the final ratio directly.
