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.
