Question
The selling price of the book is 25% more than the
selling price of the bag and the selling price of the bottle is 30% less than the selling price of the bag. If the selling price of the book is Rs.2500 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 × (125/100) = 125x SP of bottle = 100x × (70/100) = 70x => 125x – 100x = 2500 => x = 100 SP of bottle = 70 × 100 = Rs.7000 SP of bag = 100 × 100 = Rs.10000 Average = (7000 + 10000)/2 = 17000/2 = 8500
