Question

За перший місяць білка з'їла 27% запасів за другий 23% за третій 29%.Після цього в неї залишилось 63 горіхи . Скільки всього горіхів заговорила білка?

Answer 1

Всего за три месяца белка съела  27+ 23 + 29 = 79 % запасов орехов.
63 ореха осталось,  это 21 %.
Пусть Х - количество заготовленных орехов, тогда
Х = ( 63 : 21 ) * 100
Х = 300
Ответ : белка заготовила 300 орехов. 

Answer 2

Problem Analysis

The problem states that a squirrel ate 27% of its food supply in the first month, 23% in the second month, and 29% in the third month. After this, the squirrel had 63 nuts left. We need to determine the total number of nuts the squirrel had initially.

Solution

Let's assume the total number of nuts the squirrel had initially is x.

In the first month, the squirrel ate 27% of its food supply, which is equal to 0.27x nuts. In the second month, the squirrel ate 23% of its remaining food supply, which is equal to 0.23 * (x - 0.27x) nuts. In the third month, the squirrel ate 29% of its remaining food supply, which is equal to 0.29 * (x - 0.27x - 0.23 * (x - 0.27x)) nuts.

After these three months, the squirrel had 63 nuts left. We can set up the equation:

x - 0.27x - 0.23 * (x - 0.27x) - 0.29 * (x - 0.27x - 0.23 * (x - 0.27x)) = 63

Now, let's solve this equation to find the value of x.

Calculation

x - 0.27x - 0.23 * (x - 0.27x) - 0.29 * (x - 0.27x - 0.23 * (x - 0.27x)) = 63

Simplifying the equation: x - 0.27x - 0.23x + 0.0621x - 0.29x + 0.0783x - 0.0678x = 63 0.4425x = 63 x = 63 / 0.4425 x ≈ 142.45

Answer

The squirrel initially had approximately 142.45 nuts.

Note: The answer is rounded to two decimal places for simplicity.
