B Correct answer
Explanation

Ram: 0.9*CP1 = 14000 => CP1 = 14000/0.9 = 140000/9. Janu: 1.3*CP2 = 14000 => CP2 = 14000/1.3 = 140000/13. Ratio CP1:CP2 = (140000/9) / (140000/13) = 13:9.

AI explanation

Using the cost price formula, Cost Price = Selling Price * 100 / (100 - Loss%), Ram's cost price is 14000 * 100 / 90, which equals Rs. 140000/9. Janu's cost price is calculated as 14000 * 100 / 130, equaling Rs. 140000/13. The ratio of their cost prices is (140000/9) : (140000/13), which simplifies directly to 13 : 9.
