Problem Analysis

We are given the following information: - The price of a pencil is 20 lei. - The price of a portfolio is 10 times more expensive than the pencil. - The price of a computer is 100 times cheaper than the portfolio.

We need to find the price of the computer.

Solution

Let's start by assigning variables to the given prices: - Let p be the price of the pencil. - Let pf be the price of the portfolio. - Let c be the price of the computer.

From the given information, we can write the following equations: 1. pf = 10 * p (The price of the portfolio is 10 times more expensive than the pencil). 2. c = pf / 100 (The price of the computer is 100 times cheaper than the portfolio).

To find the price of the computer, we need to substitute the value of pf from equation 1 into equation 2.

Calculation

Substituting pf = 10 * p into c = pf / 100, we get: c = (10 * p) / 100

Simplifying the equation, we have: c = p / 10

Since the price of the pencil is given as 20 lei, we can substitute p = 20 into the equation to find the price of the computer:

c = 20 / 10 = 2 lei

Therefore, the price of the computer is 2 lei.

Answer

The price of the computer is 2 lei.
