Problem Statement

В магазин привезли 135 кг вермишели в 9 одинаковых коробках. До обеда продали 3 коробки вермишели, а после обеда 4. Сколько всего килограммов вермишели продали в этот день? Решите задачу двумя способами.

Solution 1: Using Total Weight of Vermicelli in the Boxes

To solve this problem, we can calculate the total weight of vermicelli sold by summing the weights of the boxes sold before and after lunch.

1. Calculate the weight of vermicelli in each box: 135 kg / 9 boxes = 15 kg per box. 2. Calculate the weight of vermicelli sold before lunch: 3 boxes * 15 kg per box = 45 kg. 3. Calculate the weight of vermicelli sold after lunch: 4 boxes * 15 kg per box = 60 kg. 4. Calculate the total weight of vermicelli sold: 45 kg + 60 kg = 105 kg.

Therefore, a total of 105 kilograms of vermicelli were sold on that day.

Solution 2: Using the Number of Boxes Sold

Alternatively, we can calculate the total weight of vermicelli sold by multiplying the number of boxes sold before and after lunch by the weight of each box.

1. Calculate the weight of vermicelli in each box: 135 kg / 9 boxes = 15 kg per box. 2. Calculate the total weight of vermicelli sold before lunch: 3 boxes * 15 kg per box = 45 kg. 3. Calculate the total weight of vermicelli sold after lunch: 4 boxes * 15 kg per box = 60 kg. 4. Calculate the total weight of vermicelli sold: 45 kg + 60 kg = 105 kg.

Therefore, a total of 105 kilograms of vermicelli were sold on that day.

Both methods yield the same result, which is 105 kilograms of vermicelli sold on that day.
