Problem Analysis

The problem states that an Arab person was asked how much money they have. They responded by saying that their money is 2/3 of their brother's money, their brother's money is 2/3 of their father's money, their father's money is 2/3 of their grandfather's money, and all of them together have one million and twenty-five dirhams. The question is to determine how much money the person has.

Solution

Let's break down the information given step by step:

1. The person's money is 2/3 of their brother's money. 2. The brother's money is 2/3 of their father's money. 3. The father's money is 2/3 of their grandfather's money. 4. The total amount of money they all have together is one million and twenty-five dirhams.

To solve this problem, we can work backward from the total amount of money and calculate the amount of money at each step.

Let's assume the person's money is represented by x.

1. The brother's money is 2/3 of x, so the brother's money is (2/3)x. 2. The father's money is 2/3 of the brother's money, which is (2/3)(2/3)x = (4/9)x. 3. The grandfather's money is 2/3 of the father's money, which is (2/3)(4/9)x = (8/27)x.

Now, we know that the total amount of money they all have together is one million and twenty-five dirhams. So we can set up the equation:

x + (2/3)x + (4/9)x + (8/27)x = 1,000,025

To solve this equation, we can find a common denominator and simplify:

(27/27)x + (18/27)x + (12/27)x + (8/27)x = 1,000,025

(65/27)x = 1,000,025

Now, we can solve for x:

x = (1,000,025 * 27) / 65

Calculating this expression, we find that x ≈ 416,675.

Therefore, the person has approximately 416,675 dirhams.

Answer

Based on the given information, the person has approximately 416,675 dirhams.

Please note that the above solution assumes that the given information is accurate and that the calculations are correct.
