Calculation of the Original Price of the Set of Christmas Decorations

To calculate the original price of the set of Christmas decorations on March 31, we need to work backwards from the given information.

We know that on April 1, the price of the set was reduced by 10%. Then, on May 1, the price was reduced by an additional 10%, resulting in a final price of 243 rubles.

Let's assume the original price of the set on March 31 was x rubles.

On April 1, the price was reduced by 10%, which means it became 90% of the original price: 0.9x rubles.

On May 1, the price was reduced by another 10%, which means it became 90% of the price on April 1: 0.9 * 0.9x = 0.81x rubles.

According to the given information, the final price on May 1 was 243 rubles. Therefore, we can set up the following equation:

0.81x = 243

To find the value of x, we can solve this equation:

x = 243 / 0.81

Calculating this, we find that the original price of the set of Christmas decorations on March 31 was approximately 300 rubles.

Please note that the search results provided by You.com did not contain specific information about the original price of the set on March 31. Therefore, the calculation above is based solely on the given information and assumptions.
