Ram buys 10 articles and sell to Mohan. The cost price of 10 articles is equal to selling price of 9 articles and Mohan sells all the article to Tripti at the cost price 9 article is equal to selling price of 8 articles. Ram’s cost price is how much percent more or less than Tripti’s cost price. Correct Answer 20% less
Calculations:
For Ram
Let the cost of 10 articles be Rs. 10.
Selling price of 10 articles = 10/9 × 10 = Rs. 100/9
For Mohan
Cost price of 10 articles = Rs. 100/9
Selling price of 10 articles = 9/8 × 100/9 = 100/8 = Rs. 12.50
For Tripti
Cost price of 10 articles = Rs. 12.50
Ram’s cost price is how much percent more or less than Tripti’s cost price = (2.50 × 100)/12.50 = 250/12.50 = 20% less
∴ Ram’s cost price is 20% less than Tripti’s cost price.
