Question
A store offered two successive discounts of 8% and 5% on
a television and still made a profit of 22%. Find the approximate cost price of the television if the marked price is Rs. 50,000.Solution
ATQ, Marked price of the television = Rs. 50,000 Selling price of the television = (50000 × 0.92 × 0.95) = Rs. 43,700 Cost price of the television = (43700/122) × 100 = Rs. 35,819.67 or Rs.35,820
