Directions for questions 12-15: Nandu and Mohan decided to sell their Apple Series watches each at ₹ 42,000 to Karthik and Ganesh respectively. In each case the selling price of ₹ 42,000 was arrived at by increasing the cost price by 25%. While Nandu gives a discount of 10% on the first ₹ 12,000, 8% on the next ₹ 16,000 and 5% on the rest to the buyer Karthik, Mohan gives a discount of 8% on the first ₹ 16,000, 7% on the next ₹ 8,000 and 5% on the rest to his buyer Ganesh. These discounts were however subject to the condition, that the buyers make the payment on time, failing which the discount gets reduced by 1% for every delay of a week. If Nandu and Mohan got all the payments on time, what is the approximate percentage of profit of the person getting the higher profit?
