Question

Привезенные на рынок арбузы можно распределить на груды по 10, или 12 арбузов без остатка. Сколько арбузов привезли на рынок , если их больше 300, но меньше 400

Answer 1

Ппц! легкотня! Если делится на 10 занчит в конце числа БУДЕТ 0 !!!соответственно мы имеем числа 310 - 390 проверяем какие числа делятся на 12 ( 360 : 12 = 3 ) вот и всё
ОТВЕТ 360

Answer 2

Calculation of the Number of Watermelons

To determine the number of watermelons brought to the market, we need to find a number that is both greater than 300 and less than 400, and is divisible by both 10 and 12 without a remainder.

Let's break down the problem step by step:

1. Find the smallest number greater than 300 that is divisible by 10 and 12: - The smallest number divisible by both 10 and 12 is their least common multiple (LCM). - The LCM of 10 and 12 is 60.

2. Find the largest number less than 400 that is divisible by 10 and 12: - The largest number divisible by both 10 and 12 is their greatest common divisor (GCD). - The GCD of 10 and 12 is 2. - Divide 400 by the GCD to get the largest number: 400 / 2 = 200.

3. Calculate the number of watermelons: - The number of watermelons is the difference between the largest and smallest numbers divisible by both 10 and 12: 200 - 60 = 140.

Therefore, the number of watermelons brought to the market is 140.
