Question
The average price of three items of furniture is Rs. 15000. If their prices are in the ratio 3:5:7, the price of the cheapest item is:
Solution
To solve this problem, we first need to understand that the average price of the three items is the total price divided by the number of items.
Step 1: The total price of the three items is Rs. 15000 * 3 = Rs. 45000.
Step 2: The prices of the items are in the ratio 3:5:7. This means the total price is divided into 15 parts (3+5+7).
Step 3: The price of one part is Rs. 45000 / 15 = Rs. 3000.
Step 4: The price of the cheapest item is 3 parts, so it is Rs. 3000 * 3 = Rs. 9000.
So, the price of the cheapest item is Rs. 9000.
