Answer 1

1, 250*20/100=50 руб это эти 20%
2, 250+20=300 руб. стоит билет в театр

4000-20/100=800 руб составила уценка
4000+800=4800 руб первоначальная цена чайника

6000*10/100=600 руб это 10%
6000*5/100=300 руб это 5%
6000-600-300=5100 руб будет стоить телевизор после второго снижения

Answer 2

1) 300 рублей
2) 5000 рублей
3) на 20 процентов
4) 5130 рублей

Answer 3

Task 1: Билет в кино и билет в театр

To find the cost of a ticket to the theater, which is 20% more expensive than a ticket to the cinema, we can use the following steps:

1. Determine the cost of a ticket to the cinema, which is given as 250 rubles. 2. Calculate 20% of the cost of a ticket to the cinema by multiplying it by 0.2. 3. Add the result from step 2 to the cost of a ticket to the cinema to find the cost of a ticket to the theater.

Let's calculate it:

1. The cost of a ticket to the cinema is 250 rubles. 2. 20% of 250 rubles is 50 rubles (250 * 0.2 = 50). 3. Adding 50 rubles to the cost of a ticket to the cinema, we find that the cost of a ticket to the theater is 300 rubles.

Task 2: Стоимость электрического чайника

To find the initial price of the electric kettle, given that its price after a 20% discount is 4000 rubles, we can use the following steps:

1. Determine the price of the electric kettle after the discount, which is given as 4000 rubles. 2. Calculate the original price of the electric kettle by dividing the price after the discount by 0.8.

Let's calculate it:

1. The price of the electric kettle after the discount is 4000 rubles. 2. Dividing 4000 rubles by 0.8, we find that the initial price of the electric kettle was 5000 rubles.

Task 3: Черешня и абрикосы

To find the percentage by which cherries are more expensive than apricots, given that apricots cost 150 rubles per kilogram and cherries cost 180 rubles per kilogram, we can use the following steps:

1. Determine the price difference between cherries and apricots by subtracting the price of apricots from the price of cherries. 2. Calculate the percentage by which cherries are more expensive than apricots by dividing the price difference by the price of apricots and multiplying by 100.

Let's calculate it:

1. The price of apricots is 150 rubles per kilogram and the price of cherries is 180 rubles per kilogram. 2. The price difference between cherries and apricots is 180 - 150 = 30 rubles per kilogram. 3. Dividing 30 rubles by 150 rubles and multiplying by 100, we find that cherries are 20% more expensive than apricots.

Task 4: Снижение цены на телевизор

To find the price of the television after the second price reduction, given that the television originally costs 6000 rubles and it was reduced by 10% and then by 5%, we can use the following steps:

1. Determine the price reduction for the first reduction by multiplying the original price by 0.1. 2. Subtract the price reduction from the original price to find the price after the first reduction. 3. Determine the price reduction for the second reduction by multiplying the price after the first reduction by 0.05. 4. Subtract the second price reduction from the price after the first reduction to find the final price.

Let's calculate it:

1. The original price of the television is 6000 rubles. 2. The price reduction for the first reduction is 6000 * 0.1 = 600 rubles. 3. The price after the first reduction is 6000 - 600 = 5400 rubles. 4. The price reduction for the second reduction is 5400 * 0.05 = 270 rubles. 5. The final price of the television after the second reduction is 5400 - 270 = 5130 rubles.

I hope this helps! Let me know if you have any further questions.
