Problem Analysis

To solve this problem, we need to find the combined cost of a notebook and a diary. We are given that the notebook costs 50 rubles, which is 1/7 of the diary's cost. We need to determine the total cost of both items together.

Solution

Let's assume the cost of the diary is D rubles. According to the problem, the cost of the notebook is 50 rubles, which is 1/7 of the diary's cost. Mathematically, we can represent this relationship as:

50 = (1/7) * D

To find the value of D, we can multiply both sides of the equation by 7:

50 * 7 = D

Simplifying the equation:

350 = D

Therefore, the cost of the diary is 350 rubles.

To find the total cost of the notebook and diary together, we simply add their individual costs:

Total cost = Cost of notebook + Cost of diary = 50 + 350 = 400 rubles

So, the notebook and diary together cost 400 rubles.

Answer

The notebook and diary together cost 400 rubles.
