Question

По­сту­пив­ший в про­да­жу в ап­ре­ле мо­биль­ный те­ле­фон стоил 5000 руб­лей. В июне он стал сто­ить 3150 руб­лей. На сколь­ко про­цен­тов сни­зи­лась цена мо­биль­но­го те­ле­фо­на в пе­ри­од с ап­ре­ля по июнь?

Answer 1

5000 - 100%
3150 - х
х = 3150*100/5000 = 63%

100% - 63% = 37%

Answer 2

Calculation of Percentage Decrease in Price

To calculate the percentage decrease in price of the mobile phone from April to June, we can use the following formula:

Percentage decrease = ((Initial price - Final price) / Initial price) * 100

Given that the initial price of the mobile phone in April was 5000 rubles and the final price in June was 3150 rubles, we can substitute these values into the formula:

Percentage decrease = ((5000 - 3150) / 5000) * 100

Calculating this expression, we find that the percentage decrease in price of the mobile phone from April to June is approximately 37%.

Please note that the calculation assumes a linear decrease in price over the given period and does not take into account any other factors that may have influenced the price change.
