за три дня продал 1240,8кг.сахара,В первый день было продано 543кг.,во второй в 2раза больше чем в третий,сколько кг.сахара было продано в третий день?

Answer 1

 Пусть хкг-сколько сахара было продано за третий день, тогда за второй- 2х(кг) и собствено в первый 543кг. Всего было продано ( 543+2х+х)кг, а согласно условия 1240,8кг. Складываем уравнение:

   543+2х+х=1240,8

 543+3х=1240,8

 3х=697,8

 х=232,6

 232,6кг сахара было продано в третий день. 

 

Answer 2

543 + 2х+х =1240,8

3х+543=1240,8

3х=697,8 

х=232,6 кг в 3 день

232,6 *2 = 465,2 кг во 2 день

Answer 3

Calculation of Sugar Sold in Three Days

To calculate the amount of sugar sold on the third day, we need to analyze the information given.

According to the question, a total of 1240.8 kg of sugar was sold over three days. On the first day, 543 kg of sugar was sold. On the second day, the amount sold was twice as much as on the third day.

Let's break down the information:

- Total sugar sold in three days: 1240.8 kg - Sugar sold on the first day: 543 kg - Sugar sold on the second day: twice as much as the third day

To find the amount of sugar sold on the third day, we can set up an equation:

Let x be the amount of sugar sold on the third day.

According to the given information, the amount of sugar sold on the second day is twice as much as the third day. Therefore, we can write the equation:

2x = amount of sugar sold on the second day

To find x, we can solve the equation:

2x = 1240.8 kg - 543 kg 2x = 697.8 kg x = 697.8 kg / 2 x = 348.9 kg

Therefore, 348.9 kg of sugar was sold on the third day.
