Tip of the Day While solving Modern Maths questions, It is convenient to shift to logarithmic expressions when working with higher powers of variables. Last year's Question of the day (22-Dec-11) Himanshu bought a car and after 3 years, sold it to Kabir at 20% less than the cost price. After spending 10% of his cost price on maintenance, Kabir put his car for sale at Himanshu's cost price. Ayush wanted to purchase it at 25% discount but Kabir gave him two successive discounts of 20% and 5%, instead of allowing 25% at one go. What is the percentage point difference between Kabir's percentage loss and the percentage loss incurred by Ayush due to the successive discount?
