Question
The selling price of the book is 20% more than the
selling price of the bag and the selling price of the bottle is 20% less than the selling price of the bag. If the selling price of the book is Rs.2200 more than the selling price of the bag, then what is the average of the selling price of the bottle and bag?Solution
Let SP of bag = 100x SP of book = 100x × (120/100) = 120x SP of bottle = 100x × (80/100) = 80x => 120x – 100x = 2200 => x = 110 SP of bottle = 80 × 110 = Rs.8800 SP of bag = 100 × 110 = Rs.11000 Average = (8800 + 11000)/2 = 19800/2 = 9900
