Question

В первый день маляры израсходовали 32 одинаковые банки краски,а во второй 27 таких же банок.Во второй день было израсходовано на 15 кг меньше.Сколько краски израсходовали маляры за 2 дня?1.Сколько краски израсходовали бы маляры за тоже время работы,если бы во второй день истратили на 30 кг краски меньше, чем в первый день?

Answer 1

1) 27-15=12(б)- 2 день
2)32+12=44(б)- за 2 дня 

Answer 2

Calculation of Paint Used by Painters in Two Days

To calculate the amount of paint used by the painters in two days, we need to add up the amount of paint used on the first day and the amount of paint used on the second day.

On the first day, the painters used 32 identical paint cans, and on the second day, they used 27 identical paint cans

Therefore, the total amount of paint used in two days is 32 + 27 = 59 paint cans.

Calculation of Paint Used by Painters with a 30 kg Difference

To calculate the amount of paint used by the painters in the same amount of working time, assuming a 30 kg difference between the first and second days, we need to adjust the amount of paint used on the second day.

If the painters used 30 kg less paint on the second day compared to the first day, we subtract 30 kg from the amount of paint used on the first day.

Let's assume that the painters used X kg of paint on the first day. Then, on the second day, they used X - 30 kg of paint.

To find the value of X, we can set up an equation using the information given:

X - 30 = 15

Solving this equation, we find that X = 45 kg.

Therefore, the painters would have used 45 kg of paint in the same amount of working time if they had used 30 kg less paint on the second day compared to the first day.
