Question

Бір кісі бір бочка квасты 14 күнде ішеді ал әйелімен бірге 10 күнде ішіп бітіреді. Оның әйелі 1 бочка квасты кашна нуде битиреди

Answer 1

Әйелдің бір бочка квасты қанша күнде бітіретінін табу керек.
Алдымен олардың ішу жылдамдығын теңестіреміз.
Ua+Uә=Uж
(адам, әйел, жалпы)
U=N/t (N - бочка саны)

1/14к + 1/Tәйел = 1/10к
1/Tәйел = 1/10 - 1/14
1/Tәйел = 7/70 -  5/70
1/Tәйел = 2/70
Tәйел = 70/2 = 35 күн

Жауабы: Әйел бір бочканы 35 күнде бітіреді

The Story of a Person and a Barrel of Kvass

Once upon a time, there was a person who loved drinking kvass. This person would consume one barrel of kvass in 14 days when drinking alone. However, when drinking together with their partner, they would finish one barrel of kvass in just 10 days. The question is, how long would it take for the person's partner to finish one barrel of kvass on their own?

To solve this problem, we can use the concept of rates. Let's assume that the person's rate of drinking kvass alone is represented by x barrels per day, and their partner's rate is represented by y barrels per day.

According to the given information, the person drinks one barrel of kvass in 14 days when alone, so their rate can be calculated as:

x = 1 barrel / 14 days

Similarly, when the person drinks with their partner, they finish one barrel of kvass in 10 days. This can be represented as:

x + y = 1 barrel / 10 days

Now, we can solve these two equations to find the rate of the person's partner:

x = 1 barrel / 14 days

x + y = 1 barrel / 10 days

Substituting the value of x from the first equation into the second equation, we get:

(1/14) + y = 1/10

Simplifying the equation, we have:

y = 1/10 - 1/14

To find a common denominator, we multiply the fractions:

y = (7/70) - (5/70) = 2/70

Simplifying further, we get:

y = 1/35

Therefore, the person's partner drinks one barrel of kvass in 35 days when drinking alone.

Please note that this solution assumes a constant rate of consumption and does not take into account factors such as variations in drinking habits or the size of the barrel.
